HM Digital DM-2 Commercial Inline Dual TDS Monitor, Upgraded Model

MonitorsControllers

DM-2 Installed The DM-2 can easily be installed on any water filtration system that removes TDS to show the TDS levels of both the feed and product water. 1/4" quick-connect T-fittings are standard. (3/8" and 1/2" are also available.)

Install on industrial systems such as car washes, window washing, manufacturing, and food processing. UPGRADED APRIL 2012! The newly upgraded model features digital calibration, low battery indicator, improved accuracy, longer battery life (2 years), longer auto shut-off time (3 min), diagnostic error messaging, and shielded sensor cables. (Upgraded features below are in ***)

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 *** 3 minutes ***. 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. The DM-2 features *** digital calibration ***.

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. Digital calibration can be done individually on each line. Improved design, including an extra large, easy-to-read LCD display. Longer, waterproof, shielded cables. Variable mounting bracket.
