Triple Inline TDS Meter TRM-1
The TRM-1 Triple Inline TDS Meter from HM Digital is one of the most essential reverse osmosis accessories. This tool uses electrode probes to monitor the TDS of your reverse osmosis system in three places and lets you know exactly how the system is performing.
Using a RODI system without a TDS meter is like driving a car without a speedometer and gas gauge. At some point you will end up in trouble. With RODI systems it is TDS that you will want to monitor for performance and filter quality. If you have a single or dual DI stage we highly recommend a triple TDS meter as it will allow you to see your TDS readings in three places. We will usually suggest installing the triple TDS meter post source water, post membrane and post DI stage. These three readings will notify you when it’s time to change the RO membrane and DI resin.

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.
