Benchtop pH/ORP/Ion Meter

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.


* PH electrode  * Temperature probe  * PH buffer pouches (pH4.01/7.00/10.01)

* USB cable    * DC5V power adapter
