DM-1: In-Line Dual TDS Monitor

Product details

DM-1: In-Line Dual TDS Monitor is an in-line meter designed to display total dissolved solids (TDS) for both feed water and product water using two separate electrode probes (in and out). It’s a practical way to track RO/DI performance by quickly comparing input vs. output water quality without removing water samples. This can help you monitor when your filtration stage may be losing efficiency, supporting better consistency for aquarium water preparation.

Features:

• Shows TDS readings for feed water and product water using in & out electrode probes
• Uses advanced microprocessor technology for efficient, accurate readings
• Dual range 0–9990 ppm with defined resolution (1 ppm from 0–999 ppm; 10 ppm from 1000–9990 ppm, indicated by a blinking x10 display)
• Factory calibrated with a 342 ppm NaCl solution and can be recalibrated using a mini-screwdriver
• Auto-Off feature shuts the unit off after 10 minutes of non-use to conserve battery power
• Includes Mur-lok® Quick-Connect T-fittings for quicker installation
• Installs quickly and easily into your system plumbing
