Eutech Expert pH Waterproof Pocket Tester – pH & Temperature, 0.0–14.0 pH
The Eutech Expert pH pocket tester from Thermo Scientific measures pH from 0.0 to 14.0 with 0.1 pH resolution and ±0.1 pH accuracy, together with temperature from 0 to 50 °C. It is a rugged, everyday tester for water treatment, aquaculture, hydroponics, education and general field checks.
A large 4-digit, double-line display shows pH and temperature at the same time, with indicators for battery life, reading stability and calibration. Automatic temperature compensation corrects readings for sample temperature, so results stay comparable across conditions.
Calibration is simple, with auto buffer recognition and up to 3 calibration points. The tester is IP67 waterproof and uses a non-replaceable, single-junction pH sensor.
It runs on four A76 (LR44-equivalent) button cells, which are included, with an average battery life of about 100 hours. Auto-off after 8.5 minutes without a key press helps save battery.
