Handheld TDS Meter 0-9990 with ATC & Temp, in vinyl carrying case

The world’s most popular TDS meter, the TDS-3 is the most reliable and longest lasting meter of its kind. It has a wide range of 0-9990 ppm has a hold button to save readings until it automatically shuts off after 10 minutes of non-use. The built-in thermometer displays the temperature and also compensates TDS for differences in temperature. The unit comes in a protective vinyl case. It takes only two batteries, which have extra long life and are very easy to change. TDS is shown in a large, easy-to-read display. It is simple to use and comes factory calibrated.

  • Ideal for commercial use. Includes a carrying case with belt clip.
  • Highly efficient and accurate due to its advanced microprocessor technology.
  • Hold Function: saves measurements for convenient reading and recording.
  • Auto-off function: the meter shuts off automatically after 10 minutes of non-use to conserve batteries.
  • 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.
  • Built-in digital thermometer enables ATC: Automatic Temperature Compensation of 1 to 50 degrees Celsius (33 to 122 degrees Fahrenheit)
  • Display: large and easy-to-read LCD screen.
  • Factory Calibrated: our meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver.

Works Well, Super Easy to Use

Very simple operation. Matches the TDS reading on my RO unit, so it seems accurate at low levels. Good for general indication of water chemistry changes and when ferts may be neeeded (my tanks are all planted freshwater). Fahrenheit temp indication would be nice, but Celsius only is no big deal. Good performance, especially for a low priced meter.

Worth it

Indispensable tool. Tap water showed 200, distilled showed 1 and ro di water showed 0! For a reef aquarium knowing tds is huge for a successful tank.

TDS/Temp Meter

This meter seems to work and I've tested several water samples. I tested my water going to my RODI system, the water produced by the RODI system that has it's own TDS meter and the results are good. The results of the water leaving the RODI are identical to this TDS/Temp meter. My only problem with this meter is that the temperature is in celcius and I would of preferred Fahrenheit. I guess I missed the meter discription where it said celcius. Now I have to look at a conversion table. Other than that I'm happy and I'm sure they have a more expensive meter with a Fahrenheit reading.

TDS okay

TDS meter is just fine, however the temp meter is very slow to read and only reads in Celcius. A little dissapointed about that.

Simple to use

This TDS tester is simple to use and accurate. It helped me determine that the free RO water from my LRS was not much different then tap water. Without the tester I would have never discover this. Now I make my own RO water and have watched all my water problems that left me head scratching all but disapear.
