3Application scene
1. Environmental sampling inspection in large watershed.
2. Used by laboratory researchers.
3. Fishery aquaculture environmental monitoring.
4. Monitoring of sewage outlets in sewage plants.
5. Rivers, lakes, creeks, etc.Measurement principle
1. PH: The potential difference measured in the solution according to the working battery composed of the measuring electrode and the reference electrode, and using the linear relationship between the pH value of the solution to be tested and the working battery potential, converted to the corresponding pH value by the transmitter.
2. Residual chlorine: A microbattery measurement system consisting of two platinum electrodes and one reference electrode. During measurement, a stable potential is maintained at the measuring end of the electrode, and different measured components produce different,good linear current intensities at this potential.
3. Conductivity: Conductivity (G) is the reciprocal of resistance (R). Place two parallel plates in the solution to be tested, apply a certain potential to both ends of the plate(usually a sinusoidal voltage), and measure the current flowing between the plates. The conductivity is calculated according to Ohm's law.
4. Turbidity:Using 90° scattering method. A near-infrared light beam of 880 nm emitted from the LED light source on the sensor is irradiated into the water sample to be detected, and suspended particles in the water sample are scattered to form scattered light.
