High precision benchtop pH/Ion meter, 5 points calibration, automatic help message displays. The meter is suitable for measuring
the pH, ORP and ion concentration of the liquids.

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.
Others 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.
Accessories:
* PH electrode * Temperature probe * PH buffer pouches (pH4.01/7.00/10.01)
* USB cable * DC5V power adapter
