HM Digital TRM-1: Triple Inline TDS Monitor

The TRM-1 is a unique monitor offering the user 3 points of contact during the filtration process. This TDS monitor allows for checking TDS levels at 3 points, such as with DI/RO (deionization / reverse osmosis), multiple points in an RO system, and more. FEATURES Displays TDS levels of the three sensing points with electrode probes Highly efficient and accurate due to its advanced microprocessor technology Auto-Off function conserves battery power. The unit shuts off automatically after 10 minutes of non-use Dual Range 0-9990 ppm (From 0 – 999 ppm the resolution is 1 ppm. From 1000 to 9990 ppm, the resolution is 10 ppm, indicated by a blinking ‘x10’ image.) Factory Calibrated: calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver Comes equipped with three 1/4 inch T-fittings (also available with 3/8″ or 1/2" T-fittings) SPECIFICATION Range: 0-9990 ppm Accuracy: ±2% Conversion Factor: NaCl (avg. 0.5) Cable Length: 24.5″ (includi
