Measure the untreated water coming in vs. the purified water going out of your Reverse Osmosis system at any time. This is important in determining when the RO membranes need to be changed.

Factory calibrated: all meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated.

Comes equipped with a 1/2" inlet and 3/8" outlet. Quick Connect T-fittings for Merlin-Garden Pro or Tall Blue-Merlin for quick install.
