The Hach Lange DR1900 Portable Spectrophotometer can survive any environment. It is both dust and water repellent. It is structured to enable it to performs well in any location. While in the field, you may meet dust and wet scenarios that will make other machines fail. The DR1900 has been made with considerations of the field such that it has a simple to use screen and a user interface that is efficient even in tough places. Below the coarse exterior, it has more than 220 most familiar water analysing methods already installed.

To analyse what you consider important, you are able to come up with your own user friendly ways of analysing. The DR1900 spectrophotometer works at a wavelength of 340 to 800 nm. This makes it possible to get results that can usually only be found when laboratory apparatus are used. Please note: LCK Cuvette test can be done, though this should be without barcode reading & 10 fold measurement feature.
