HACH Portable Visible Spectrum Spectrophotometer
Model: DR 1900

Feature
• 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 can test in the most demanding conditions.
 
Includes: basic printed instrument manual, dust cover, 1-in. square matched glass sample cells, AA alkaline batteries 4/pk and a four-type adapter set. Power Module
