MTU high-precision turbidity meter

● Monitoring of water supply plant before, after, filtration, sedimentation and factory outlet monitoring ● Municipal water quality monitoring ● Industrial process discharge and recycling water quality monitoring, circulating cooling water monitoring, activated carbon filter water monitoring, membrane filtration water monitoring, boiler feedwater monitor

The MTU high-precision turbidity meter strictly follows the ISO7027 international standard and uses the 90 ° scattering principle for measurement. After focusing the light emitted from the sensor light source assembly, it enters the turbidimeter downward, and encounters the suspended particles in the sample to generate scattered light. The photodetector can detect the scattered light at an angle of 90 ° with the incident beam. The scattered light The value is proportional to the turbidity of the measured sample. The sensor is designed with a bubble removal device, which can remove the air bubbles entrained in the sample stream, thereby eliminating the most significant interference in low turbidity measurement.

● Built-in bubble elimination system, which can eliminate the interference of bubbles to the measured value to the greatest extent;

● Digital sensor supporting Modbus protocol, plug and play, strong anti-interference ability, cable length can reach hundreds of meters;

● Reliable LED light source with a lifetime of up to 100,000 hours;

● The cleaning and maintenance is very simple, and it is corrected once every three months;
● The meter can provide one isolated RS232 digital interface and one isolated RS485 digital interface, supporting standard Modbus ASCII and Modbus RTU protocols;
● Programmable relay output: Any relay can be set to high alarm, low alarm, and timer modes;
● With the function of automatic saving of historical data, it can store and query historical data information for 10 years.
