Only one probe is required with this meter to measure pH, pH-mV (to check the electrode status), ORP and temperature, simultaneously. With all other instruments you need to switch the pH electrode with an ORP electrode (or vise-versa). The compact instrument fits in the palm of your hand and the bottom probe connections ensures the electrode cable does not get in your way. The unique Sensor Check™ feature 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.The included pH/ORP temperature probe features an easy to clean recessed tip that prevents solids in solutions from collecting on the sensor. The AISI 316 stainless steel and titanium body of these probes function as a potential matching pin for increased stability of readings and extended sensor life.
