VisionPlus pH618N is the successor of the popular pH618 advanced pH tester with IP67 body, temperature readout, 50 data point storage, menu driven operation and replaceable electrode module. VisionPlus pH618N takes useful features typically found in larger, portable meters and packed them into a small, easy to use package. ?Available in two different models: one for degree Celsius temperature readout and one for Fahrenheit temperature readout.

VisionPlus pH618N is RoHS compliant.
