The Milwaukee CD97 Conductivity/TDS Tester with ATC and 1 Point Manual Calibration, 0 to 1000 ppm, +/- 10 ppm is an easy-to-use instrument that measures quick and reliable pH, EC or TDS values. Measuring electrical conductivity is the best way of checking the amount of salt or dissolved solids (TDS) in water.

This tester allows users to measure from very low to very high conductivity solutions and compensates for the temperature variance automatically (ATC).

The CD97 is specifically designed for water analysis. The calibration procedure is very simple and fast. This tester has automatic temperature compensation, ±10 ppm accuracy and a range of 0 to 1000 ppm. CD97 comes complete with protective cap, calibration screwdriver, batteries and instructions.
