IQWQ-7M Industrial Water Quality Multi-Parameter 7-in-1 Self-Cleaning Combo Sensor Modbus RS485
- Digital sensor, RS485 Modbus/RTU communication protocol.
- Equipped with an automatic cleaning device, effectively cleaning the sensor surface, preventing microbial adhesion, resulting in more accurate measurements and lower maintenance costs.
- Optional digital sensors for dissolved oxygen, COD, conductivity/salinity, turbidity, ammonia nitrogen,PH, ORP, etc., suitable for long-term online monitoring.
- Integrated design, capable of simultaneously measuring 7 parameters (including temperature).
The IQWQ-7M online multi-parameter self-cleaning digital sensor features an integrated design, ensuring reliability and ease of use. lt can simultaneously measure up to 7 parameters, with selectable sensor types including dissolved oxygen, COD, pH, ORP, conductivity/salinity, Ammonia nitrogen, and Turbidity. It utilises an RS485 Modbus/RTU communication protocol, allowing direct data transmissionto the data acquisition platform.
This online multi-parameter water quality sensor is equipped with an automatic cleaning device. The automatic cleaning interval and number of cleaning cycles can be set to adapt to different water quality levels. The automatic cleaning device effectively cleans the sensor surface, preventing microbial adhesion and significantly reducing maintenance costs. Each sensor is equipped with a quick-connect, waterproof connector for easy assembly and disassembly.
The front sensor protective cover protects the internal sensor fromdamage. The cover has slots around its perimeter to effectively prevent large suspended particles and organisms from damaging the sensor probe without affecting measurement accuracy.
