  • PCTD02 Turbidity/TSS/MLSS Controller

PCTD02 Turbidity/TSS/MLSS Controller

This Turbidity/TSS/MLSS controller is a smart online chemical analyzer,widely used in Thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food, tap water and other industries. TheTurbidity sensor, based on the infrared absorption scattered light method and combined with the application of ISO7027 method, can guarantee the continuous and accurate detection of turbidity. Based on ISO7027, infrared double scattering light technology will not be affected by chroma for the measurement of turbidity value. According to the usage environment, self- cleaning function can be equipped with. It assures the stability of data and reliability of performance; with the built-in self-diagnosis function, it can make sure the accurate data be delivered; besides, the installation and calibration is quite simple.

The Turbidity transmitter can be used to display data measured by the sensor, so the user can get the 4-20mA analog output by transmitter’s interface configuration and calibration. And it can make relay control, digital communications, and other functions a reality.
