SH-OIL200 Oil in Water digital sensor
Overview
SH-OIL200 Oil in Water digital sensor adopts specific UV monochromatic light to stimulate aromatic hydrocarbon compounds and compounds containing conjugated double bonds in petroleum to emit fluorescence, receiving its fluorescence signal through highly sensitive photoelectric sensor, and obtains the density of oil in the water body according to the proportionality relationship between fluorescence intensity and algal density. The device has digital intelligent design, adopts RS485 interface and standard Modbus protocol, comes with cleaning brush and temperature compensation, and has the functions of calibration, recording, analysis and diagnosis.
Product features
- Measurement without reagents, no pollution, more economical and environmentally friendly
- Self-cleaning function removes influence of oil and air bubbles, maintenance-free
- Optical and digital filtering technology to eliminate the influence of stray light
- Corrosion-resistant housing, waterproof grade IP68, can work underwater for a long time
- RS485 communication interface, standard Modbus protocol for easy integration.
