DM-3 In-Line Dual EC/TDS Monitor

The DM-3 is a commercial-grade EC/TDS monitor measuring EC/TDS feed (input) water vs. product (output) water of a water filtration system at any time. DM-3 has a large backlit screen that you will be able to see the readings in dark environments. With its shielded cables and diagnostic messaging this robust device is ideal for Reverse Osmosis (RO), Deionized water (DI) filtration systems that work well in applications such as drinking or potable water, Water treatment, Aquariums, Hydroponics, and many more

Features:

1. Highly efficient and accurate due to its advanced microprocessor technology

2. Displays TDS levels of the Feed Water and Product Water with in & out electrode probes

3. Auto-Off function conserves battery power (Shuts off automatically after 3 minutes)

4. Factory Calibrated: our meters are calibrated with a 342 ppm NaCl solution. The DM-3 features digital calibration

5. Diagnostic error messaging

6. Shielded sensor cables

7. Comes equipped with two 1/4 inch T-fittings (Also available with 3/8″ or 1/2″ fittings)
