overview

The new spectral sensor has a diameter of60mmThe sensor contains a set of precise spectral analysis components, which can accurately analyze the organic pollution concentration at the inlet, biochemical tank or discharge outlet of municipal sewage plants in the ultraviolet visible bandCOD、BOD、TOC、DOC、SACIt can also be testedTSSTotal suspended solids concentration, nitrate nitrogen, and nitrite nitrogen concentration. Easy to use, no need for reagents, no need for sample pretreatment.

The patented optical system design ensures measurement accuracy, stability, and reliability. The drift free sensor ensures reliable data even after long-term use without the need for routine maintenance. Using a complete full spectrum length range from200nmarrive720nmperhaps200-390nmCompared to the single wavelength or multi wavelength principle, it has better measurement results and compensation for interfering materials such as turbidity. The built-in ultrasonic cleaning system reduces manual window cleaning time and can also add compressed air cleaning for special harsh environmental applications. Using high-tech materials-Titanium alloy andPEEkIt can be used in very harsh environments and has a long service life.

measuring principle

The basic working principle is UV visible continuous spectral scanning. When a beam of light passes through the test liquid, any substance in the liquid will absorb the light, reducing the intensity of the transmitted light. The instrument measures the absorbance at different wavelengths to depict the absorption curve. By analyzing the absorption curve, the test component can be qualitatively and quantitatively tested. At the same time, solid particles in the liquid will scatter light in various directions, causing a decrease in the intensity of transmitted light (at all wavelengths). Continuous spectral scanning can effectively compensate for the influence of changes in the background composition of the tested liquid. The probe tested using this method has a certain testing interval and cannot be tested continuously.

WTWThe spectral sensor adopts an optical design, with a symmetrical measurement system and reference system, the same optical elements, light intensity, light quantity, and optical path length, so it has automatic drift compensation and does not require conventional zeroing.

NitraVis /CarboVis /NiCaVisOptical sensors can automatically adjust the flicker frequency of the light source according to different samples, ensuring that the light signal is neither too strong nor too weak, with a very low signal-to-noise ratio and reliable measurement data.
