HI8424 Portable Waterproof pH/ORP/Temperature Tester
HI8424 portable pH analyzer, with excellent waterproof performance and easy operation, is a very popular acidity analyzer. HI8424 can measure pH, ORP, and temperature, with the advantages of high measurement accuracy and fast response speed. The instrument has three built-in calibration points (pH 4.01, 7.01, 10.01), and automatic calibration recognition can avoid calibration errors. Power on self-test, displaying battery level. The ORP electrode can be used to measure the oxidation-reduction potential and automatically select the resolution. The instrument uses rechargeable batteries and can be equipped with an induction charger. Users can choose to turn on or off automatic shutdown, sound prompts, and backlight functions. Press the HOLD key to activate the reading lock function, which can lock the reading for easy recording.
