pH electrode, Edge Digital, Glass, Refillable, Matching Pin.

The HI-11311 electrode features a built-in microchip that stores sensor type, ID, and calibration information that is automatically retrieved by Edge once the electrode is plugged in.

Stored pH calibration information includes: calibrated buffers, date, time, offset and slope characteristics of the electrode.

The HI-11311 features an easy to plug in 3.5mm connector and is recommended for use in laboratories and as a general purpose pH electrode.

When HI-11311 is used with Edge the impedance of the pH measuring electrode is checked in real-time to notify you in the event of glass breakage. During calibration Sensor Check technology checks the state of the junction. The reference junction is also evaluated and reported on the display.

3.5 Connection – Phono plug electrode connection used on HANNA smart Edge electrodes. Provides a secure, easy-to-use connection.

All electrodes and probes have 6 months warranty.
