Features
It adopts 1200L/mm high-performance UV special grating, imported tungsten lamp, large-scale integrated digital circuit, and new monochromator structure to make the instrument more stable and reliable.
The large sample room can optionally accommodate a 10cm cuvette, which is particularly suitable for low-content analysis in water plants, power plants, and sugar plants.
The host machine not only has a photometric test function, but also has a fixed-position test function. It uses the standard substance control method and the standard coefficient method to directly measure the concentration of the sample.
This series of products has stable quality and high cost performance, and is a good model for laboratory equipment.
