pH Mode:
- 1 to 5 points push-button calibration with auto-buffer recognition.
- Selectable pH buffer options or using the custom calibration solutions.
- Automatic electrode slope display helps user decide whether to replace sensor.
ORP Mode:
- 1 point offset calibration allows adjusting the displayed value to a known standard.
- Relative and absolute mV measurement modes provide accurate ORP readings.
Ion Concentration Mode (For PH-930):
- 2 to 5 points calibration providing the 8 concentration points can be selected.
- Automatically recognize ion electrodes, does not need to specify the type of ion.
- Selectable multiple concentration units include the ppm, mg/L and mol/L.
Other Features:
- Auto-Hold function freezes stable reading for easy viewing and recording.
- Automatic electrode diagnosis shows offset and electrode slope.
- Expanded memory stores and recalls up to 500 readings.
- Built-in real-time clock stamps stored data to meet GLP standard.
