Overview
Novo ZS-600 (flow type) online Turbidity Meter is used to measure the degree of obstruction of suspended solids in water to the transmission of rays of light, and can detect turbidity caused by soil, dust, microorganisms, etc. Sensor calculates turbidity by emitting light waves, measuring transmitted light and scattered light intensity, using RS485 interface communication, accurate data, strong anti-interference, support calibration and automatic cleaning functions.
Features
1. Large screen dot matrix LCD display, support Chinese and English menu switching
2. Built-in bubble elimination system (flow type), improve Measurement accuracy and Stability
3. Good reproducibility, not affected by sample flow rate and pressure (immersion type)
4. Invisible near monochrome Infrared source, avoid chroma and external light interference, built-in luminosity compensation
5. With water storage function, ensure that the water sample is left in the internal circulation tank of the Sensor for 24 hours (circulation type)
6. Adopt new detection technology to avoid external light interference and have strong anti-interference ability (immersion type).
7. The light path uses high light transmitance quartz Glass lens, and the infrared light wave emission and reception are stable
8. Optional RS-485 communication interface (MODBUS protocol partial compatibility), 4-20mA current output value can be arbitrarily set
9. Photoelectric isolation 4-20mA current output
10. The function of setting the lag amount arbitrarily avoids frequent operation of the relay
11. Adopt multi-point correction method
12. Automatic cleaning interval can be set (Sensor support required)
13. Watch dog function to ensure that the meter does not crash
14. Core components come from foreign brands
15. Power failure protection > 10 years
Principle
Sensor emitters transmit light waves. After absorption, reflection and scattering of the measured object during transmission, part of the transmitted light is irradiated to the 180 ° direction Detector, and part of the scattered light is irradiated to the 90 ° direction Detector. The turbidity value is calculated by measuring the intensity of the transmitted light and the scattered light, combined with its relationship with the sewage turbidity.
Applications
Water treatment, environment monitoring, industrial process control
Standards
MODBUS protocol partially compatible
Steps
