Infrared scattering light technology: when a light beam is directed at the sample solution, particles within the solution scatter the light. As shown in the diagram below, the angle between the emitted infrared light and the detection path is 90° (in accordance with ISO 7027). The intensity of the scattered light received by…

Infrared scattering light technology involves directing a light beam onto the sample solution, where sludge particles scatter the light. The infrared light source emits light, and the detection path is set at a specific angle to the incident light. The intensity of the scattered light received by the detector correlates with…

When measuring a sample, the salinity sensor first obtains an accurate conductivity value, which is then converted into salinity through an internal algorithm. Conductance or resistance is determined by measuring the current and voltage across the electrodes of the conductivity cell. Conductance (G) is defined as the reciprocal…

Infrared scattering light technology involves directing a light beam onto the sample solution, where suspended solids scatter the light. The infrared light source emits light at a specific angle relative to the detection path. The intensity of the light received by the detector correlates with the concentration of suspended…

The redox sensor uses a platinum electrode as the indicator electrode, and an Ag/AgCl reference electrode forms a galvanic cell with the water sample. The redox potential of the platinum electrode relative to the saturated Ag/AgCl reference electrode is measured with an electronic millivoltmeter, then converted to the redox…

The sensor collects the potential difference between the reference electrode and the glass hydrogen ion indicator electrode, as well as the resistance value from the thermistor to obtain the water temperature. Based on the Nernst equation, the potential is then converted into a pH value.
