Pocket Water Resistant pH/ORP/°C
HI98121 simultaneously measures pH, redox potential and temperature. Housed in a compact and perfectly waterproof case, it combines ease of use and measurement safety. When switched on, the instrument performs a self-test indicating the battery charge level in%, thus avoiding any measurement error due to too low a power supply. A stability indicator will alert the user that the measurement is stationary and suitable for reading.
HI98121 comes with a tool for replacing the probe and batteries.
