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)

Seriously, you need one of these if you are getting RO water from your LFS or grocer. It is a major player in the reefer's tool box.
