Low turbidity analyzer FSTU5320-L adopts the principle of 90º scattered light, suitable for low-turbidity occasions such as tap water and secondary water supply
FESKS Online Low Turbidity Analyzer FSTU 5320-L type usesPrinciple of 90º scattered light. By guiding light emitted by the light source downward into the water sample in the sensor, the light is scattered by suspended particulate matter in the water sample, and the scattered light at an angle of incidence of 90 degrees is received by a silicon photovoltaic cell receiver immersed in the water sample. The turbidity value of the water sample is obtained by calculating the relationship between the 90-degree scattered light and the incident light beam.
Product characteristics
▶ Corrosion-resistant, anti-fouling and easy-to-clean metallic texture process
▶ Imported chip components ensure stable and reliable instrument measurement
▶ BeltLED-backlit large dot matrix LCD display
▶ Automatic identification sensor
▶ 2 channels of 4 - 20 mA current outputs, the corresponding values can be arbitrarily set
▶ One-way multi-function relay, with cleaning, periodic alarm, error alarm functions
▶ Two sets of independent relays set Hi/Lo alarm points, which are divided into upper and lower limits
▶ SupportRS485 Modbus RTU standard protocol
▶ Historical curve, measurement data storage and record query functions (500,000 sets of data)
▶ Various installation methods: disk mounting/Wall mount installation/Pipeline installation
meter application
A wide range of products are used in online monitoring of turbidity in rivers and lakes such as tap water, secondary water supply, sewage, and reclaimed water reuse.
☞ This controller needs to be connected to KSNT 532 Sensor is used together
