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, while the drift free sensor ensures reliable data even after prolonged 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.

Automatic cleaning

NitraVis /CarboVis /NiCaVisOptical sensors have multiple cleaning methods, including ultrasonic cleaning or compressed air cleaning, as well as composite mode ultrasonic cleaning+Compressed air cleaning. The sensor will automatically select the cleaning cycle. If you choose to blow with air, you need to set the corresponding relay function.

Ultrasonic cleaning system

The probe is equipped with an ultrasonic cleaning system as standard, which ensures long-term reliable operation and saves maintenance. Optical lenses will vibrate slightly under the action of ultrasound, which can effectively prevent pollutants from adhering to the optical lenses, greatly improving the stability and reliability of testing.

Air blowing device (optional)

When the on-site conditions are extremely harsh, it is recommended that users choose another set of high-pressure air blowing device to achieve dual safety and ensure the reliable operation of the system.

structure

Refer to the figure below, from the light source1The emitted light passes through a lens2After diffusion, it enters the measuring cell in the form of parallel light3, then through a converging lens4 After focusing, it reaches the detector5Generate sensing signals. In the figure,6To measure the signal, there is a test liquid passing through it,7As reference signals, without testing the liquid, these two sets of signals are received by photodiodes and converted into current signals, which are then converted into the required component concentrations through certain algebraic operations.
