HM Digital TDS-EZ Water Quality TDS Tester, 0-9990 ppm Measurement Range, 1 ppm Resolution, 3% Readout Accuracy

Product Description: A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS-EZ can tell you your overall water purity level, which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS-EZ is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The TDS-EZ is a great tool for drinking water, water filtration and purification, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, and more.

Product Features

  • Economy model that is ideal for end-users. Highly efficient and accurate due to its advanced microprocessor technology.
  • Hold Function: saves measurements for convenient reading and recording and battery life is approx. 1000 hours of usage and power source is 2 x 1.5V button cell batteries (included) (LR44 or equivalent)
  • Auto-off function: the meter shuts off automatically after 10 minutes of non-use to conserve batteries. Display: large and easy-to-read LCD screen.
  • Measurement Range: 0-9990 ppm. From 0-999 ppm, the resolution is in increments of 1ppm. From 1000 to 9990 ppm, the resolution is in increments of 10ppm, indicated by a blinking ‘x10’ image. Fun, translucent blue housing that’s very strong and durable.
  • TDS-EZ meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver. Includes a TDS chart sticker on the back of the meter that explains TDS values.

  1. Wildly varying readings depending on temperature (no ATC) Don’t buy a TDS meter without ATC (automatic temperature compensation)! Models with ATC are only a few dollars more.I foolishly bought this based on the number of 5 star reviews and didn’t know about how much the liquid temperature will affect the readingFor tap water that is around 200-300 ppm (typical) you can see a 50ppm difference in just 10 degrees (F) temperature change.Here are some readings at various temperatures:temp TDS53F 23057F…

  2. Convenient, simple to use. Not temperature compensated. Very easy to use and is accurate enough for my needs. Values match the values shown by the tds display on my RO unit’s in/out readings to the DI stage.Update: I have realized that there is a unit available on amazon for just a couple of dollars more than this unit. From what I can gather, the TDS-4 is essentially the same unit but has temperature compensation…
