SEM9850-TMOnline water quality transparency analyzer
Online water quality transparency analyzermeasuring principle
The transparency of water bodies is an important indicator for determining the level of black and odorous water. The sensor is based on the combined infrared absorption scattering method. The infrared light emitted by the light source is scattered by the water sample, and the electrical signal detected by the photoelectric monitor is converted into a transparency value. The sensor is equipped with an automatic cleaning device, which ensures accurate data measurement and can quickly reflect changes in water transparency.
Functional Features
- The sensor adopts dual beam infrared scattering photometry detection technology, which has good repeatability and stability;
- Built in self diagnosis function to ensure accurate data;
- Optional cleaning brush with automatic cleaning function, greatly reducing sensor maintenance;
- Digital sensors with strong anti-interference ability and long transmission distance;
- Standard digital signal output, which can be integrated and networked with other devices without a transmitter;
- The on-site installation of sensors is convenient and fast, achieving plug and play functionality;
- Reverse polarity protection for sensor power supply;
- sensorRS485 A/BTerminal misconnection power protection;
- Equipped with time display, data storage, and historical data viewing functions;
- Optional wireless data transmission module
Typical applications
- Transparency is an important indicator for determining the level of black and odorous water bodies, especially suitable for online monitoring of transparency in black and odorous water bodies;
- Suitable for online monitoring of water transparency in urban inland rivers, lakes, reservoirs, and other surface waters, as well as in the aquaculture industry;
