Product Introduction
PHECT is a multifunctional sensor integrating pH, electrical conductivity, and temperature sensing. Installed in liquids, it can continuously monitor subtle changes in these three parameters online. The sensor has a built-in microprocessor for digital signal processing and temperature compensation of the probe. The communication interface uses standard RS485 and supports Modbus RTU protocol, facilitating integration with various control systems. The probe is detachable for easy replacement, suitable for water quality monitoring in aquaculture, pool monitoring, industrial production, food and pharmaceutical, and water purifiers.
