Portable pH/mV/Temperature Meter
The HI 8314 is a portable pH meter designed to be rugged and easy-to-use, yet reliable and practical. It is ideal for education and for measurements on the field. Simple pH calibration is performed manually through 2 trimmers. Measurements are automatically compensated for variations in temperature. The meter shows the reading together with the current mode (pH, mV or °C). A low battery indicator will alert the user when the battery needs to be replaced.
Two models are available:
- HI 8314 uses pH electrodes with DIN connector and internal temperature sensor
- HI 83141 is provided with separate connectors for pH electrode (BNC) and temperature probe
