SM-1: In-Line Single TDS Monitor

Product details

SM-1: In-Line Single TDS Monitor is a compact, battery-powered meter designed to measure Total Dissolved Solids (TDS) in RO/DI systems. It displays TDS levels of both the feed water and the product water, using in-line electrode probes placed to read each stream. Practically, it helps you quickly verify water quality changes as your system runs, such as comparing incoming water to treated output. The unit is factory calibrated for dependable readings and can be recalibrated when needed. With quick-connect fittings included, it’s intended for straightforward installation in standard RO/DI plumbing setups.

Features:

• Displays TDS levels for feed water and product water using in-line electrode probes (with in or out placement).
• Uses advanced microprocessor technology for highly efficient and accurate readings.
• Auto-Off function shuts the meter down after 10 minutes of non-use to help conserve battery power.
• Single measurement range of 0–9990 ppm, with selectable resolution behavior indicated by a blinking “x10” at higher values.
• Factory calibrated with a 342 ppm NaCl solution, with recalibration available.
• Includes Mur-lok® Quick-Connect T-fittings for faster installation.
• Compact design supports easy mounting in RO/DI lines.
• Runs on included batteries for extended monitoring between changes.
