ZS-600 Industrial Online Turbidity Detector Introduction: Turbidity is the degree of obstruction caused by suspended solids in water to the transmission of light. Water containing soil, dust, fine organic matter, and other microorganisms and colloids can cause turbidity in the water. The light waves sent by the transmitter on the sensor are absorbed, reflected, and scattered by the measured object during transmission, and a portion of the transmitted light can shine on the detector in the 180 ° direction, while a portion of the scattered light scatters on the detector in the 90 ° direction. The intensity of light received on detectors in the 180 ° and 90 ° directions is related to the turbidity of the tested wastewater. Therefore, the turbidity of the wastewater can be calculated by measuring the intensity of transmitted and scattered light. This product uses RS485 interface to communicate with digital sensors, with high data accuracy and strong anti-interference. It can directly control the calibration and automatic cleaning functions of digital sensors. Features: 1. Large screen dot matrix LCD display, supporting Chinese and English menus (switching between each other). 2. Built in bubble elimination system (flow type) to improve measurement accuracy and stability. 3. Good reproducibility, unaffected by sample flow rate and pressure (input type). 4. Stable invisible near-monochromatic infrared light source is used to avoid the interference of chromaticity in the liquid and external visible light on sensor measurement; And built-in photometric compensation to improve measurement accuracy. 5. Equipped with water storage function, ensuring that there is water sample left in the internal flow tank of the sensor for 24 hours (flow type). 6. Adopting the latest detection technology to avoid interference from external light, with strong anti-interference ability (immersion type). 7. Using quartz glass lenses with extremely high transmittance on the optical path makes the emission and reception of infrared light waves more stable. 8. Communication function (optional): Equipped with RS-485 communication interface (partially compatible with MODBUS protocol), the corresponding value of 4-20 mA current output can be set arbitrarily. 9. Optoelectronic isolation 4-20mA current output. 10. The hysteresis value can be set arbitrarily to avoid frequent action of the switch relay, and there is a function to set the switch value to close and close. 11. Use multi-point correction method. 12. The automatic cleaning interval can be freely set (supported by sensors). 13. Watchdog function: Ensure that the instrument panel does not crash. Technical indicators: Measurement range: 0-200NTU (flow through), 0-10000NTU (submerged), customizable range (adaptive according to sensor range) Resolution: 0.001NTU~1NTU (adaptive based on sensor resolution) Accuracy: ± 2% FS Repeatability: ± 1.0% Control interface: Two sets of ON/OFF relay contacts, divided into high point and low point alarm signals for photoelectric isolation output.
