Optical water quality sensor COD

for environmental analysisindustrialreal-time

This COD intelligent sensor is with RS485 communication interface and Modbus RTU standard protocol. The sensor supports the simultaneous measurement of COD and turbidity. It measures COD through a beam with a wavelength of 254 nm, and turbidity through a beam with a wavelength of 546 nm. Features and Benefits 1.Corrosion-resistant shell; the threaded interface on NPT3/4 is easy to install. 2.It has an automatic cleaning function, which can remove the interference of attachments on the optical glasses. 3.It adapts the double-beam measurement technique to ensure the accuracy and stability of the measurement. 4.It has the long-life infrared LED light source, the lamp decay phase is 5 years, and the service life is more than 10 years. 5.It has calibration record storage function, plug and play, no need to calibrate for the first use. 6. The sensor supports hot swap function.
