High quality pH meter for Sentron ISFET probes. The SI400 / SI600 meters' advanced electronics can achieve an accuracy of 0.01 pH, a level that is sufficient for most field and laboratory applications. A large backlit 3.2" LED colour display allows convenient determination of measurement values and provide clear information for operation. The pH value is displayed in a large front and is continuously displayed during menu operation. The intelligent wizard simplifies the calibration process, reducing calibration time and the chance for errors. A full calibration report is displayed at the end of the procedure.

For advanced users, bias setting can be manually defined and the current pH value stored and recalled at a later time. The meter contains built-in user definable auto screen-off and auto-off settings that prevent screen burn-in and extend battery time.

The devices also have several integrated options for connection of accessories and mounting (e. g. on a stand). The USB port is well protected by a tightly sealing cover and the casing and battery door are fitted with rubber seals.
