Hach DR1900 Portable Spectrophotometer

 The DR1900 excels in the field because it is the lightest and most compact portable spectrophotometer. Your field testing takes you to potentially dusty and wet conditions where other equipment simply won’t be safe. The DR1900 is built for rugged conditions, and it’s flexible, --accepting the widest range of vial sizes. Built with field use in mind, the DR1900 has a large, clear screen and a simple user interface that makes testing easier than ever in even the most demanding conditions. Easy to hold, and operate, the compact DR1900 is a valuable tool for your field technicians.

Underneath the rugged exterior, the DR1900 has the largest number,-- over 220-- of the most commonly tested preprogrammed methods already built in. You can also use the easy-to-use interface to create your own methods. 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: TNTplus vial test evaluation possible, but without barcode identification & 10 fold measurement and outlier elimination.

The DR1900 combines the ruggedness and portability of a field instrument with over 220
of the most commonly tested water methods.

• Carry Anywhere
  The lightest, most compact portable spectrophotometer available easily goes where you need to go.
• Test What You Need
  Analyze your water with more preprogrammed methods than any other portable spectrophotometer, or easily create your own methods to suit your unique needs.
• Ensure Accuracy in the Field
  Wavelength range of 340 to 800 nm. provides accuracy typically seen only in laboratory instruments.
• Make Testing Easier
  Simple, easy-to-use interface plus the widest range of vial sizes makes testing flexible.
• Take Into Field Environments
  Rugged construction keeps the elements out, which means you can test in the most demanding conditions.
