DR1900  PORTABLE SPECTROPHOTOMETER  HACH     ATAU  COLORIMETER

The DR1900 excels in the field because it is the lightest and most compact portable spectrophotometer.
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.
