Multiple & portable water quality instrument LH-M900 adopts the method of spectrophotometry, which supports the wavelengths of 420nm, 470nm, 520nm, and 620nm, and can support multiple parameter detection. Many experiments show that this method is simple, quick, and sensitive. The instrument is small in size, light, and easy to carry, suitable for field and work field use. By adopting imported sensors, and advanced optical systems, and expanding the measuring range of colorimeters, the time needed for sample dilution is saved. Test items can be freely matched according to customer requirements.
