The PCTestr™ 35-Series Posket Meter combines testing for pH, conductivity and temperature in one convenient unit.

All of the multi-parameter testers in the Testr 35 Series are ideal for either field or lab use.  The rugged body is waterproof and will even float if dropped ina field or stream.

Advanced features of this pocket meter include up to 5 pointpH calibration with NIST or USA auto-buffer recognition, auto-shut-off, and user-adjustable temperature coefficient.
