Pen-type pH/ORP meter GPH70 1 piece

The backlight colour changes depending on the operating situation (blue during measurement, green during calibration, red during alarm). It has automatic temperature compensation, so temperature can be measured simultaneously during measurement. When the measurement value stabilizes, a smiley face will appear. It floats on water, so it can be easily retrieved when dropped in water. Measurement items: pH, temperature, ORP Measurement range: pH/0-14.00, temperature/0-50℃, ORP/0-1000mV Measurement accuracy: pH/±0.01±1digit, temperature/±0.5℃, ORP/±0.2% FS Resolution: pH/0.01pH, temperature/0.1℃, ORP/1mV Functions: Backlight, Hold, Auto Power Off (8 minutes), Low Battery Indicator Proofreading: 1-3 points Temperature compensation: automatic temperature compensation (0-50℃) Dust and water resistance: IP67 Power supply: 4 AAA batteries (included for testing) Size (mm): Φ40×178 Weight(g): 133 Accessories: Standard solution/pH4.01, pH6.86, vial, KCL solution, 4 dry batteries, strap *ORP measurement requires the separately sold ORP sensor 1 (4-355-11).
