The HI11310 is a glass body, refillable, double junction pH electrode. This electrode includes a built-in temperature sensor for temperature compensated measurements in a single probe design. Within the probe there is an integrated microchip that stores calibration data, electrode type, and serial number, which allows for changing of sensors without having to recalibrate. The HI11310 is a general purpose pH electrode and is designed for use with Hanna’s edge^® pH/EC/DO meter.
