Description:

Digital oil-in-water sensor, a digital sensor developed based on the ultraviolet fluorescence optical water quality analysis platform. The sensor emits ultraviolet light of a specific wavelength. When certain petroleum substances in the water sample absorb ultraviolet energy and become excited, they will emit fluorescence when they jump back from the high energy state to the low energy state. The intensity of the excited fluorescence is related to the concentration of the substance to be measured. The sensor has RS485 output, standard MODBUS protocol, and supports various terminal networking.

Features:

Ultraviolet fluorescence method
On-site plug and play
Built-in cleaning brush
Waterproof grade IP68
