Electrical Conductivity readings in water are a great way to measure the purity, or the concentration of a solution. The HM Digital DM-2EC is great for almost all water filtration systems, especially Reverse Osmosis Deionization systems where two points of readings may be necessary to judge the quality and performance of the system. The meter includes, easy to use, push connect fittings that will let you place each probe in-line with 1/4” RO tubing.




Range: 0-9990 µS Dual Range – Measures from 0-999 µS, with a resolution of 1 ppm. From 1000 to 9990 µS, the resolution is in 10 µS increments, indicated by a blinking ‘x10’ image.

Accuracy: ±2%

Cable Length: 46″ (including sensor), shielded cables

Sensor: Dual, 1/4″ diameter for quick-connect fittings (model SP-3, included)
