Water Quality Monitoring Sensor Series Products (Part Two)

（1）Digital Residual Chlorine Sensor ZWIN-LCL1006

Product introduction:

The digital residual chlorine sensor is an instrument used to measure the concentration of residual gas in water samples. Residual chlorine refers to the remaining chlorine in the water, including free chlorine and combined chlorine. It is the chlorine used to kill bacteria and other micro organisms during the disinfection process. Usually based on electrochemi-cal or optical principles. Electrochemical sensors determine residual gas concentration by measuring the current produced by the reaction between gas and electrodes. Optical sensors determine chlorine concentration by measuring its absorption or scattering of  light of specific wavelengths.

（5）Digital chlorophyll Sensor ZWIN-CHL1006

Product introduction：

The working principle of this sensor is to use the characteristics of chlorophyll in the spectrum. By emitting light of a specific wavelength to illuminate the water body, chlorophyll will release fluorescence of another wavelength after absorbing the energy of the light. Then the intensity of this fluorescence is measured by using relevant detection technology. The fluorescence intensity is proportional to the content of chlorophyl in the water body, so the concentration of chlorophyll can be indirectly determined. lt has a self-cleaning function to remove attachments in water samples, maintenance-free, no sample processing and extraction, non-destructive, reagent-free, pollution-free, accurate measurement, low detection limit, and good long-term stability. Long-life LED light source, built-in optical attenuation compensation, longer sensor life. Plug and play, no calibration required for first use.

（6）Digital Blue-Green Algae Sensor ZWIN-BGA1006

Product introduction:

The working principle of this sensor is usually based on the fluorescence method. When a certain wavelength of excitation light is used to illuminate the water body, the pigment in the blue-green algae will be excited to a high energy state. When it returns to the ground state from the high energy state, it will emit fluorescence greater than the excitation wavelength, and the excited fluorescence intensity is related to the concentration of blue-green algae. By detecting this fluorescence intensity, the content of blue-green algae in the water body can be indirectly determined. It has a self-cleaning function to remove attachments in water samples, maintenance-free measurement, low detection limit, good long-term stability, ultra-bright LED light source, improve sicnal-to-noise ratio, enhance stability, plug and play, and no calbration is reguired for the first use.
