DM-2: Commercial In-Line Dual TDS Monitor
FEATURES
-
Highly efficient and accurate due to its advanced microprocessor technology.
-
Displays TDS levels of the Feed Water and Product Water with in & out electrode probes.
-
Auto-Off function conserves battery power. The unit shuts off automatically after 20 seconds.
-
Dual Range - Measures from 0-999 ppm, with a resolution of 1 ppm. From 1000 to 9990 ppm, the resolution is in 10 ppm increments, 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 1/4 inch Mur-lok® Quick-Connect T-fittings. Also available with 3/8" or 1/2" fittings.
-
Installs quickly and easily.
Differences from the DM-1:
-
Designed for commercial/industrial applications.
-
Stronger, water-resistant casing.
-
Calibration can be done individually or simultaneously on each line.
-
Improved design, including an extra large, easy-to-read LCD display.
-
Longer, waterproof, shielded cables.
-
Variable mounting bracket.

NOTE: All water purification and filtration systems are different. Please contact the manufacturer of your RO or DI system to determine when you should change your filter cartridges or membranes (based on TDS levels and/or percent rejection).
| With a TDS monitor or meter, you can easily determine your RO system's performance by calculating the percent rejection. Once you have obtained the TDS levels of your feed water (IN) and product water (OUT), use the calculator below to determine the percent rejection of your RO system. |
