PCE Instruments PH 23 Waterproof Digital pH Meter 0.00 to 14.00 pH

Model # PH 23

The waterproof Digital pH Meter PCE-PH 23 is used for rapid fluid analysis. The Digital pH Meter offers the possibility to determine the temperature and the pH value.
The operation of the Digital pH Meter PCE-PH 23 is done via the four buttons on the front. The probe installed in the Digital pH Meter can be exchanged easily by loosening the fixing ring from the device and only removing the probe.
Due to the waterproof and robust ABS housing (IP67), the Digital pH Meter can also be used under harsh environmental conditions. The re-calibration of the Digital pH Meter ensures permanent high accuracy and is very easy to perform using the optionally available calibration sets (automatic calibration function without calibration screws).
