Only one probe required with this meter to measure pH, pH-mV (to check the electrode status), ORP and temperature, silmutaneously. With all other instruments you need to switch the pH electrode with an ORP electrode (or vise-versa). This pH meter is largely used to control plating bath waste water, swimming pool water quality and potable water sanitizing processes. Unique Sensor Check feature that allows the user to establish the status of the pH electrode before performing measurements. The Sensor Check feature consists of a pH-mV scale that shows the characteristics (slope and offset) of the sensor, allowing the user to determine if the electrode is in good condition.

 

This pH meter is protected in a waterproof casing for use in humid and wet environments. It also features a large dual-level LCD that displays pH or ORP and temperature readings simultaneously.
