How do I use a TDS meter?<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"What_is_a_TDS_meter\"><\/span><span style=\"font-weight: 400;\">What is a TDS meter?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">A TDS meter is a small handheld device which measures the amount of dissolved solids in your water. You dip the meter in a glass of water and a number appears on the end of the meter which shows a number. This is measured in parts per million (ppm).\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To understand this better, think of the TDS meter as a thermometer. When you use a thermometer on a person, it measures the temperature of the body and tells you if the person has a fever or not. It doesn\u2019t diagnose why or how the person has a fever. This is very similar to how a TDS meter measures the dissolved solids in your water.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_does_a_TDS_meter_work\"><\/span><span style=\"font-weight: 400;\">How does a TDS meter work?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Dissolved salts and minerals carry a tiny electrical charge, so the more of them in your water, the better it conducts electricity. The two metal probes at the tip of the meter pass a small current through the water and measure how easily it flows. The meter then converts that conductivity into a TDS number in ppm.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Here\u2019s the catch. The meter doesn\u2019t actually <\/span><i><span style=\"font-weight: 400;\">see<\/span><\/i><span style=\"font-weight: 400;\"> what\u2019s in your water. It only reads conductivity and does the maths. That\u2019s why it can tell you how much is dissolved, but not what is dissolved.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Types_of_TDS_meters\"><\/span><span style=\"font-weight: 400;\">Types of TDS meters<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Not all TDS meters look alike. Here are the ones you\u2019re most likely to come across.<\/span><\/p>\n<p><b>Handheld pen meters:<\/b><span style=\"font-weight: 400;\"> These are the most common and the most affordable. They\u2019re slim, run on small batteries and fit in a drawer. If you only want to check your water once in a while, this is the one to pick.<\/span><\/p>\n<p><b>Meters with a temperature display:<\/b><span style=\"font-weight: 400;\"> Conductivity changes with temperature, so these meters show the water temperature along with the TDS reading. Some also adjust the reading for temperature automatically, which makes the result a little more reliable.<\/span><\/p>\n<p><b>Built-in or inline meters:<\/b><span style=\"font-weight: 400;\"> Some water purifiers come with a TDS meter fitted into the system, which shows the reading without you having to dip anything. It\u2019s convenient, but it usually reads only the water in that particular line, so a handheld meter is still handy for checking your tap water.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_do_you_need_before_you_start\"><\/span><span style=\"font-weight: 400;\">What do you need before you start?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Did you imagine wearing a lab coat and walking into a chemistry lab to measure the TDS of your water? It\u2019s not a difficult process. Just gather these.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>A clean glass:<\/b><span style=\"font-weight: 400;\"> Use a glass or a steel tumbler that has been rinsed well. Leftover soap or old water can throw off your reading.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Fresh batteries:<\/b><span style=\"font-weight: 400;\"> Weak batteries can give you odd or fluctuating numbers. If your meter has been lying around for months, check it first.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Your water sample:<\/b><span style=\"font-weight: 400;\"> Fill the glass with enough water to cover the probe up to the marked line.

A high reading doesn\u2019t automatically mean the water is harmful, and a low reading doesn\u2019t automatically mean it\u2019s safe. Think of the number as the first clue, not the final verdict. (If you\u2019d like to know more, read our TDS full form blog on safe TDS levels.)<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Test_tap_water_vs_purified_water\"><\/span><span style=\"font-weight: 400;\">Test tap water vs. purified water<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Here\u2019s a simple trick. Test your tap water first. Then test the water that comes out of your purifier. Compare the two numbers.<\/span><\/p>\n<p><b>If you have an RO purifier:<\/b><span style=\"font-weight: 400;\"> The purified water should show a clearly lower TDS than your tap water. If the two numbers are almost the same, your RO membrane may not be working properly, and it\u2019s time to get it checked.<\/span><\/p>\n<p><b>If you have a UV or UF purifier:<\/b><span style=\"font-weight: 400;\"> Don\u2019t be surprised if both readings are nearly the same. UV and UF purifiers neutralise bacteria and viruses but don\u2019t remove dissolved solids. A similar TDS reading is normal here, and it doesn\u2019t mean the purifier is faulty.<\/span><\/p>\n<p><b>If the purified water reads very low:<\/b><span style=\"font-weight: 400;\"> An RO purifier strips the water of minerals, so the reading can be quite low. This is why a mineraliser cartridge adds calcium and magnesium back to the water. A reading that rises slightly after the mineraliser stage is a good sign.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_a_TDS_meter_cant_tell_you\"><\/span><span style=\"font-weight: 400;\">What a TDS meter can\u2019t tell you?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">A TDS meter is useful, but it has its limits. It cannot detect:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Bacteria and viruses:<\/b><span style=\"font-weight: 400;\"> These are living organisms and don\u2019t change the conductivity of your water in a meaningful way. Water with low TDS can still carry them.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Arsenic and fluoride:<\/b><span style=\"font-weight: 400;\"> These can be dangerous in higher amounts, and a TDS meter can\u2019t tell you whether they\u2019re present.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Pesticides and other chemicals:<\/b><span style=\"font-weight: 400;\"> Organic contaminants like pesticides and fertiliser run-off won\u2019t show up on a TDS meter.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">So if you\u2019re unsure about your water source, or you live in an area with known contamination, get your water tested in a lab. A TDS meter is a good quick check. A lab test is the complete picture.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_to_do_if_your_TDS_is_high_or_very_low\"><\/span><span style=\"font-weight: 400;\">What to do if your TDS is high or very low?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><b>If your TDS is high (above 500 ppm):<\/b><span style=\"font-weight: 400;\"> Use an RO purifier. RO (Reverse Osmosis) pushes water through a membrane under high pressure and leaves the dissolved solids behind. Boiling, candle filters and activated carbon don\u2019t reduce TDS, so don\u2019t rely on them here.<\/span><\/p>\n<p><b>If your TDS is very low:<\/b><span style=\"font-weight: 400;\"> Water with a very low TDS can taste flat and has fewer minerals. This is common after RO purification. The fix is a mineraliser, which adds calcium and magnesium back so your water is both pure and good for you.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_DrinkPrime_helps\"><\/span><span style=\"font-weight: 400;\">How DrinkPrime helps?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Whether your TDS reading is high, low or somewhere in between, DrinkPrime has a purifier made for your city\u2019s water. The range includes Copper, Alkaline, Mineral+, UV and Under-The-Sink purifiers. Since 100% RO strips the water of essential minerals, a mineral cartridge adds calcium and magnesium back to the RO-treated water.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">DrinkPrime\u2019s purifiers come on a rental basis. The monthly subscription starts at \u20b9349\/month, with a refundable security deposit of \u20b91,500. (Only the Under-The-Sink model has a security deposit of \u20b91,999.) The rental covers the product, installation, delivery, maintenance and relocation. All recharges can be made on the app, which also helps you track your filter\u2019s health and total water usage.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">So grab a TDS meter, test your water, and if the number worries you, DrinkPrime takes care of the rest.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span><span style=\"font-weight: 400;\">Frequently Asked Questions<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h2><span class=\"ez-toc-section\" id=\"1_How_do_I_use_a_TDS_meter\"><\/span><b style=\"font-size: 16px;\">1. How do I use a TDS meter?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Switch it on, dip the probe in a glass of clean water up to the marked line, stir gently, wait for the number to settle and note the reading.<\/span><\/p>\n<p><b>2. Can I test hot water with a TDS meter?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">It\u2019s best not to. Temperature affects conductivity, so let the water come to room temperature for a more reliable reading.<\/span><\/p>\n<p><b>3. What TDS reading is safe for drinking water?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A reading of 0-200 ppm is considered completely safe. Between 201 and 500 ppm, water is still acceptable as per BIS norms, but the taste might be affected.<\/span><\/p>\n<p><b>4. Is a TDS meter accurate?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">It\u2019s accurate enough for a quick check, but it estimates TDS from conductivity and is not a lab result. It cannot detect bacteria, viruses or specific metals.<\/span><\/p>\n<p><b>5. Why is my purified water\u2019s TDS still high?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">If you have an RO purifier, the membrane may need servicing. If you have a UV or UF purifier, it\u2019s normal, because these don\u2019t remove dissolved solids.<\/span><\/p>\n<p><b>6. How often should I check my TDS?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">When you move to a new home, when your water source changes, after the seasons change if you use borewell water, and after your purifier has been serviced.<\/span><\/p>\n<p><b>7. Can a TDS meter tell me if my water is free of bacteria?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">No. A TDS meter only measures dissolved solids.
