HM Digital DM-3: In-Line TDS Meter

HM Digital DM-3: Commercial In-Line TDS Meter

This In-Line Dual TDS Monitor is highly efficient and accurate due to its advanced microprocessor technology. Displays TDS levels of the Feed Water and Product Water with electrode probes.

Install on industrial systems such as a car washes, window washing, manufacturing, and food processing. This model features digital calibration, low batter indicator, improved accuracy, longer batter life (2 years), longer auto shut-off time (3min), diagnostic error messaging, and shielded sensor cables. (Upgraded features below in red.)

Standard 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 funtion 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

Diagnostic error messaging

Shielded sensor cables
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.

Strong, 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.
