Product details
Product Introduction
MQ-Turb01 is a turbidity/suspended solids digital sensor that uses RS485 communication interface and standard Modbus protocol. Corrosion resistant shell, IP68 protection level, suitable for various harsh working environments; Using infrared LED as the light source, unaffected by the chromaticity of the water sample, adopting a 90 ° scattering method, in compliance with NFEN872 and NFT901052 standards; Digital modulation filtering technology to eliminate the influence of ambient light; Bubble compensation algorithm to reduce bubble interference in water samples; Long life infrared LED light source, lasting for more than 10 years; Automatic switching between high, medium, and low ranges to improve measurement accuracy; RS485 communication interface, standard Modbus protocol, easy to integrate.
Sensor usage, maintenance, and upkeep
1. Sensor cleaning
The sensor adopts a 90 ° inclined surface design, which is not easy to attach dirt and can be regularly rinsed with clean water;
2. Calibration of sensors
To ensure accurate measurement, regular calibration is required. Clean the sensor thoroughly before calibration, calibrate the zero point of the sensor in pure water, and then perform the second point calibration based on 80% of the required measurement range.
3. Storage of sensors
The sensor should be cleaned thoroughly before storage, leaving no residual water. The sensor should be stored in a dry environment.
