KWS-700B Online pH Sensor | Aquaculture Water Quality Monitoring
Introduction
KWS-700 series pH sensor uses long-life industrial online electrodes and a built-in temperature sensor for automatic temperature compensation, making it suitable for long-term online monitoring. The sensor uses RS485 communication interface and standard MODBUS protocol, which can be easily networked and integrated without a controller. It is widely used in water quality treatment, hydrological monitoring, wastewater treatment, swimming pools, industrial control, biology and other fields.
Feature
- Digital sensor, RS-485 output, standard MODBUS protocol;
- No electrolyte required, strong anti-interference, no need for frequent calibration;
- Built-in temperature sensor, automatic temperature compensation;
- Adopt high-performance industrial online electrode, can work stably for a long time;
- Built-in calibration parameters, accurately calibrated at factory, can be directly installed and used.
