Dual Inline TDS Meter DM-1
The Dual inline TDS Meter is one of the most important reverse osmosis accessories that allows you to measure the TDS in two places and lets you know exactly how the system is performing. We suggest installing the “in” electrode after the membrane and the “out” electrode after the DI resin stage. These two readings allow you to monitor filter performance/quality and will notify you when it’s time to change the RO membrane and DI resin.
Features:
- Displays TDS levels of the feed water and product water with in & out electrode probes.
- Highly efficient and accurate due to its advanced microprocessor technology.
- Auto-Off function conserves battery power. The unit shuts off automatically after 10 minutes of non-use.
- Dual Range 0-9990 ppm (From 0 – 999 ppm the resolution is 1 ppm. From 1000 to 9990 ppm, the resolution is 10 ppm, indicated by a blinking ‘x10’ image.)
- Factory Calibrated: calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver.
- Comes equipped with Quick-Connect T-fittings to install inline.
- Installs quickly and easily.

Installation Instructions:
- Turn the source water off and relieve any pressure in your RODI units lines.
- Determine the location that you want to install your probe. Certain models come with multiple probes that can be fitted in different places throughout your RODI system. Please see below for suggested locations.
- Cut the RO tubing where you wish to install the metering probes and install the push connect “T” fitting so that water flows through the straight side of the fitting.
- Push the probe into the “T” fitting so that the metering tips are perpendicular to the flow of water for the best results.
- Once the probe is installed slowly turn your source water back on and check for any leaks around the fittings.
