Nobo - Model NS-ZS603 -Low Range Digital Turbidity Sensor
The water contains soil, silt, fine organic matter and other microorganisms and colloids that cause turbidity in the water. Turbidity sensor is a sensor that detects the turbidity of water by measuring the degree of obstruction of suspended matter to light. The infrared wave transmitted by the emitter on the sensor is absorbed, reflected and scattered by the measured object during the transmission process, and a part of the transmitted light can be irradiated to the detector in the 180 °direction. The intensity of light received on the detector is related to the turbidity of the sewage being measured, so the turbidity of the sewage can be
calculated by measuring the intensity of the transmitted light. It is widely used in chemical industry, electroplating, paper making, environmental protection water treatment engineering, pharmaceutical, food, tap water and other solutions turbidity monitoring. Especially suitable for outdoor and scene using .
Notice
- Please follow the operating rules and notes of this manual when using
- If you find the sensor work abnormally or damage when using , please contact with the manufacturer and don’t repair it by yourself
- In order to make the measuring range more accuracy , the meter should always be calibrated with the sensor .If your sensor has been purchased for nearly a year or have some quality problem , please pay attention to the replacement
- Please preheat the sensor for 30 minutes before carrying out the calibration work.
Product configuration
Please confirm that the sensor and box you purchased are complete. If the package is damaged or any spare parts are in short supply, please contact the manufacturer as soon as possible
Standard configuration
- One digital submersible turbidity sensor ,cable length is 10m
- One operating manual
- Qualified certificate
- Digital submersible turbidity sensor , output RS485 and 4-20mA signal directly
