Commercial Inline Dual TDS Monitor

Ideal for water treatment as well as other industrial and commercial applications the DM-2 is the big cousin of the DM-1 with added features such as a stronger, water-resistant casing.

Commercial Inline 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.
