1. Product introduction
The UV Method COD Digital Sensor is a digital sensor developed by
our company for real-time online monitoring of water COD (Chemical
Oxygen Demand). Organic matter that causes increased COD in water
bodies absorbs ultraviolet (UV) light. This product utilizes this
characteristic to measure the degree of UV light absorption by
organic matter in water, thereby converting it to the water's COD
value. To eliminate the influence of suspended solids on UV light,
this product is equipped with automatic turbidity compensation
functionality.
2. Main features
² Stainless steel housing, high strength, corrosion-resistant
² No reagents, no pollution, more economical and environmental
protection.
² Automatic turbidity compensation function.
² Automatic cleaning function, reducing maintenance costs.
² Less maintenance, long service life and low cost of use
² can directly connect to devices with RS485 signal interfaces (e.g.,
computers, PLCs) for data acquisition. Facilitates integration of
the sensor into host computer systems and IoT systems in industrial
control environments.
² Able to configure sensor settings via RS485 communication: slave
address, baud rate, online calibration, factory reset, etc.
² Utilizes multi-point calibration method, support max 5 points
calibration.
