FAQ:
Q1. Can I use this monitor with any RO system?
A1. Yes, the TRM-1 is compatible with most RO systems and comes with standard 1/4" T-fittings (also available in 3/8" and 1/2").
Q2. Does it require frequent calibration?
A2. No, the unit is factory calibrated with 342 ppm NaCl. It retains accuracy but can be recalibrated when needed.
Q3. What does a blinking ‘x10’ mean on the screen?
A3. The blinking ‘x10’ indicates the TDS reading is in the 1000–9990 ppm range, and the resolution has shifted to 10 ppm.
