HM Digital DM-2 In-Line Dual TDS Monitor 5-Pack
The HM Digital DM-2 5-Pack In-Line Dual TDS Monitor is a water tester which is used to test the amount of total dissolved solids (TDS) in water. It is a new model of the HM DM-1 In-Line Dual TDS Monitor. The DM-2 is highly efficient and accurate due to its advanced microprocessor technology.
The HM Digital DM-2 has a multitude of improved and advanced water quality testing features. Major differences from the DM-1 include: (1) being designed for commercial and industrial applications instead of solely residential ones; (2) a stronger water-resistant casing; (3) calibration can be done individually or simultaneously on each line; (4) improved design including an extra large easy-to-read LCD display; (5) longer, waterproof, shielded cables; and (6) a variable mounting bracket.
The HM Digital DM-2 is designed for commercial and industrial applications such as food processing, manufacturing, window washing, car washes, and more. It can also be used in residential applications to determine when to change your whole house filter cartridges, reverse osmosis membranes, and so on. It comes equipped with 1/4 inch Quick-Connect T-fittings.
This Dual Range TDS monitor 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.
