Hm Digital's DM-1 In Line TDS meter is essential if you have a small R/O system.
It is critical to regularly monitor the membrane's performance by measuring its rejection rate. The DM1 will accurately and easily provide this important information. The meter's 1st probe will measure the ppm before the membrane, and the 2nd probe will measure the ppm after the membrane.
Install on systems such as aquarium r/o systems, window cleaning systems and to measure tds in and out of your r/o system.
FEATURES
Displays TDS levels of the feed water and product water with in & out 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: our meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver.
Comes equipped with John Guest Quick-Connect T-fittings as shown.
Installs quickly and easily.
