TRM-1: Triple In-Line 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), or 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.
