Measuring principle According to the 90° near-infrared light scattering turbidity measurement principle of EN27027 standard, the turbidity value under standard comparable conditions is recorded by the 90° scattered light method in the near-infrared region with a wavelength range of 880 nanometers according to ISO7027/EN27027 standard. In addition to the turbidity signal, the temperature signal is also recorded. The rays excited by the infrared transmitter ① are directed to the medium at a certain beam angle. Due to the different refraction of light between the incident window and the medium (water), the scattered radiation generated by the particles ⑤ in the medium is directed to the scattered light receiver ③④ at a certain beam angle. The measured value of the medium is constantly compared with the measured value of the reference receiver ②. The excellent interference signal suppression function of the digital filter and the self-monitoring of the sensor ensure the reliability of the measurement.
