This dissolved oxygen sensor uses fluorescence method technology. The detection head is covered with fluorescent material, and the LED light source emits blue light to the head. The fluorescent substance emits red light when excited, with higher dissolved oxygen concentrations resulting in shorter transition times from blue to red light. The sensor calculates dissolved oxygen concentration based on this phototropic relationship.
The digital DO sensor enables long-distance signal transmission without significant signal attenuation. Featuring RS485 interface with standard Modbus RTU communication protocol, it integrates seamlessly with industrial control systems.
Yes, the dissolved oxygen sensor has IP68 protection rating, allowing continuous underwater operation for extended periods.
The standard lead wire length is 1 meter. Custom lengths are available upon request, with pricing varying according to length specifications.
