The TRM-1 is a three-sensor TDS monitor that can monitor the TDS levels at three different points. It is perfect for RO/DI systems and other types of filtration and purification systems.
- 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 Mur-lok® Quick-Connect T-fittings (standard is 1/4", also available with 3/8" or 1/"2 T-fittings)
- Installs quickly and easily.
