DM-1 HM Digital Inline Dual TDS Monitor

Product Description: How Pure is Your Water? HM Digital's DM-1 is a dual inline monitor that measures TDS from 0 to 9990 ppm. It includes batteries, two sensors and two 1/4" quick-connect T-fittings. The DM-1 is an easy and convenient method of determining TDS levels for water filtration/purification systems such as reverse osmosis RO, deionization DI and more. It's very useful for coolers or under-the-sink systems. For any type of system that removes TDS, you can install the 'IN' sensor on your tap water before the system and the 'OUT' sensor on your product water after your filtration system to determine the filter/membrane's effective operating rejection rate.

The DM-1 helps you tomeasure the tap water coming in vs the purified water going outof your water filtration system at any time The In-Line Dual TDS Meterdisplays TDS levelsof the feed water and product water with in and out electrode probes This TDS Monitor is highly efficient and accurate due to itsadvanced microprocessor technology Highly efficient and accurate due to its advanced microprocessor technology Auto-Off function conserves battery power.
