TRM-1: Triple In-Line TDS Monitor
 The TRM-1 is a unique monitor that offers the user 3 points of contact during the filtration process. This TDS monitor allows you to check TDS levels at 3 points, such as with DI/RO (deionization/reverse osmosis), multiple points in an RO system, and more.

 CHARACTERISTICS
 View TDS levels at three sensing points with electrode probes
 Highly efficient and precise thanks to its advanced microprocessor technology
 The auto-off function conserves battery power.
 The unit automatically turns off after 10 minutes of non-use.
 Dual range 0-9990 ppm (From 0 to 999 ppm the resolution is 1 ppm. From 1000 to 9990 ppm, the resolution is 10 ppm, indicated by a flashing "x10" image).

 Factory Calibrated: Calibrated with a 342 ppm NaCl solution.
 Gauges can be recalibrated with a mini screwdriver. Supplied with three 1/4 inch T-fittings.
