Perfect UV–VIS Absorbing Measurement Techniques
With the method of ultraviolet absorbing spectrum, VLUV-201-N fits market demands, and gains a lot of field testing experience and marketing information feedback. Adopting the D2 lamp UV–VIS absorbing (200nm~700nm full spectrum) measurement techniques, each of the different types of water samples will have its own neural network model. Designed by the degree of IP43, pumps water samples by controlling the external water pump automatically, fits the neural network of 200-400nm spectral absorption. Working Stably and Reliably
Can be uninterrupted operation for more than 2 months since the optical online measurement with no chemical reagents, non-contact measurement, real-time monitoring and other advantages. Product Features
Adaptable and Long Maintenance Cycle
Adaptable with the environment: replaceable flow cell, which providing a diverse measurement ranges of flow cells with a 5mm ~ 30mm thickness, and different specifications to accommodate the different water qualities from surface water to the high concentration of sewage water. Having the multiple self-cleaning system. All waterways of the instrument employ corrosion-resistant materials. The smallest value or pipe size is not less than 3mm, without the risk of clogging, ensuring the maintenance cycle for at least 2 months under the high pollution, multiple contaminants, or corrosive working conditions . Can be running outdoor reliably for a long time since designed by the degree of IP43. Measure for Real-time and Zero Running Costs.
Built-in dozens of characteristic spectral lines of different water samples, collecting spectral data through self-developed high-precision fiber optic spectrometer, adopting the neural network algorithm to calculate UV absorption in real-time and accurately. Almost zero running costs, no chemicals, no secondary pollution. Automatic Calibration Function
Optical detection platform with water judgment function to prevent any misoperation. A-click operation to complete the calibration automatically, along with fuzzy neural network self-learning function. Technical parameters | Measuring Method | UV-VIS continuous spectrum water quality detection |
