TracWater Digital ORP Sensor
Overview
TracWater TW-4747A digital ORP sensor adopts a durable industrial-grade electrode, an integrated temperature sensor, and automatic temperature compensation, making it well-suited for long-term online monitoring tasks. It provides RS485 digital output and supports the MODBUS protocol, facilitating effortless networking and seamless system integration without requiring an external controller. This sensor finds widespread application in areas such as water quality treatment, hydrological monitoring, wastewater management, the chemical industry, biology, and other relevant fields.
Features
Digital sensor with RS-485 output and MODBUS protocol support.
Requires no electrolyte, exhibits strong resistance to interference, and eliminates the need for frequent calibration.
Includes an integrated temperature sensor with automatic temperature compensation functionality.
Utilises high-performance industrial-grade online electrodes designed for reliable operation over extended periods.
All calibration data is stored directly in the sensor, enabling on-site installation and immediate use.
Applications
Surface Water Monitoring: Lakes and rivers monitoring the oxidation-reduction potential to assess water quality and detect pollution. Reservoir monitoring ensures the quality of water used for drinking and irrigation.
Drinking Water Treatment: Treatment plants monitoring ORP to optimise disinfection processes and ensure safe drinking water. Distribution network monitoring tracks water quality throughout the supply network to detect and prevent contamination.
Wastewater Treatment: Treatment facilities monitoring ORP to control and optimise biological treatment processes. Industrial effluent monitoring to ensure compliance with environmental regulations by monitoring the quality of discharged water.
Agriculture: Fish farms monitoring water quality to maintain optimal conditions for fish health and growth.
Environmental Research: Ecological studies investigating the redox conditions in various aquatic environments to understand ecological dynamics.
