Product introduction
smart storm water quality sensor PHEHT description:
Sensor cartridge: The pH/ORP sensor cartridge is designed for extended service life using plastic gel technology, meaning the sensor does not require frequent calibration or replacement. The sensor is designed for the toughest conditions a pH/ORP sensor can encounter, in terms of sensor resistance, fast response time, minimal flow dependence, and low power consumption.
Digital technology: This smart digital PHEHT sensor stores historical calibration data within the sensor, enabling a 'plug-and-play' system without recalibration.
smart storm water quality sensor PHEHT features:
Digitally optimized measurement technology
Sensor combining pH, ORP & temperature
Smart sensor stores configuration settings and calibration history
Digital sensor: Modbus RS-485
Field-replaceable pH/ORP sensor cartridge
Robust and waterproof housing
smart storm water quality sensor PHEHT range:
PH：0 to 14
ORP: -1000mV to +1000mV
