DR 1900 Portable Spectrophotometer

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.
