Sponsored Ad - HM Digital TRM-1 Triple in-Line TDS Monitor

Q: Can this unit help me know when it's time to change the pre-RO carbon filters?

The best product for that application would be an in-line pressure gauge placed after the carbon filter. A drop in pressure would then indicate a need to change your pre-filters.

Q: Can I request the t to be 3/4, 1/4, 3/4? I have a very large output and don’t want to slow the flow, you know?

We have the 1/2x1/2x1/4 Tee version, please contact us direct 678-458-4815

Q: What is the accuracy rating?

Check it with Pinpoint Hardness monitor and HM TDS meter, readings within 1 ppm. It is good enough for me to check the RO unit efficiency and when to throw the valve to send the filtered water to the tank.
