The HI11311 electrode features a built-in microchip that stores sensor type, serial number, and calibration information. It also features a single ceramic junction and the spherical pH sensing portion is made with high temperature glass. This design consideration is ideal for general purpose laboratory use. This probe features a 3.5 mm connector designed exclusively to be used with Hanna Instruments edge® Tablet Meters.

The smart chip in edge’s digital electrode remembers its last calibration. Get real-time diagnostics with Cal Check for probe condition and Sensor Check so you will immediately know if the probe is damaged. The built-in temperature sensor makes automatic temperature compensation standard.

Matching Pin
The HI11311 integrates a matching pin into the electrode and is part of the Hanna Instruments Sensor Check™ feature. The matching pin checks the impedance across the indicating and reference electrodes. This allows
