DR1900 Portable Spectrophotometer

Lab methods in the palm of your hand

With over 220 pre-programmed Hach methods in a waterproof, shock tested design this spectrophotometer delivers lab quality results in a portable, field ready instrument.


Product Description

The spectrophotometer excels in the field because it is designed to go where you need to go. Your field testing takes you to potentially dusty and wet conditions where other equipment simply will not last. Built with the field in mind the instrument has a large easy-to-ready screen and a simple user interface that makes testing easier than ever, even in the harshest conditions. Underneath the rugged exterior, the spectrophotometer has over 220 of the most commonly tested water methods already built in. If you want, use the easy-to-use interface to create your own methods to test what is important to you. Tests are performed with a wavelength range of 340 to 800 nm which make this a field instrument you can use to find results typically only seen in laboratory instruments.
Please note: LCK cuvette test evaluation possible, but without barcode reading & 10 fold measurement feature.

  • Carry anywhere due to a compact design
  • Test what you need with hundreds of built-in methods
  • Ensure accuracy in the field
  • Make testing easier with a clear, easy-to-use interface
  • Test in demanding environments – water and dust-proof design
