HANNA® Instruments Portable Waterproof pH Meters

Automatic 1- or 2-Point Calibration

IP67 waterproof rated. Hanna Portable Waterproof pH Meters have a stability indicator and hold feature to let you know when to take the reading and then freeze it for recording measurements. Feature probes with a built-in amplifier, making them impervious to electrical noise interference. The Sensor Check feature shows you a pH-mV scale with the slope and offset of the sensor to determine if your electrode is in good condition. Each pH Meter comes with an electrode, pH 4 and 7 buffer sachets, 2 x 20mL electrode cleaning solution, three 1.5V AA batteries, instructions and carrying case.
Nos. 143439 and 143440 have pH, ORP and temperature sensors housed in a titanium body.
No. 143440 also allows you to see pH in mV for diagnostic aid purposes. The waterproof casing is good for wet and/or humid environments but is not IP67 rated.
