H2O Purification : In-line TDS Meter

You no longer need to guess when to change the filters on their RO water treatment systems. The In-Line TDS Meter will give you accurate readings of TDS on the tap water coming in or the purified water going out of their system at any time. The microprocessor controlled electrodes give accurate readings (+/- 2 %) between 0 and 9990 ppm. All meters come factory calibrated and can be recalibrated with a mini-screwdriver if necessary. The in and out probes are housed in John Guest Quick-Connect 1/4” T-fittings on 24 1/2” cables for easy installation and auto-off function will help to prolong life of included batteries.
