AquaLabo PHEHT pH digital sensor, 3 m, bare wire, without cartridge

PHEHT is a digital pH sensor from the DIGISENS range, designed for hard conditions in rivers, seawater and wastewater. The reference electrode uses PONSEL's PLASTOGEL electrolyte, which is in direct contact with the water without a porous junction, so it cannot clog and never needs refilling.

The measuring part is a replaceable cartridge holding the pH glass, the temperature sensor and, in the PHEHT cartridge, a platinum ring for ORP. This sensor is supplied without cartridge: choose a PHEHT cartridge (PF-CAP-C-00155) for pH, ORP and temperature, or a pHT cartridge (PF-CAP-C-00616) for pH and temperature.

The calibration and a log of the last ten calibrations are stored in the sensor. It connects to ACTEON transmitters, ODEON and NEON handhelds or a PLC over Modbus RS-485 or SDI-12.
