Its durable enclosure is water resistant up to IP 67 and can be used in adverse weather conditions. Recalibration of the device always ensures that readings are accurate and it is easy to do with the help of the calibration kit. The automatic calibration is done via the keypad and without the need for calibration screws. This pH Meter has an electrode integrated into its enclosure and the readings are adjusted automatically for temperature compensation.
