Descripción
SUMMARY
A small, lightweight, portable spectrophotometer that uses dedicated reagents to measure a variety of items quickly and easily.
The DR1900 is perfect for use in the field because it is the lightest and most compact portable spectrophotometer. It also can perform that largest number of tests of any portable instrument.
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. Also, it is flexible because you can use the widest range of vial sizes of any other spectrophotometer.
FEATURES
Portability - Easy to hold, and operate, the compact DR1900 is a valuable tool for your field technicians. This is lightest and smallest spec on the market.
Accuracy - 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.
Ruggedness - The DR1900 is built for rugged conditions. Built as a hand-held spec the DR1900 has a large, clear screen and a simple user interface that makes testing easier than ever in even the most demanding conditions.
- Compact and lightweight (B5 size, weight 1.5 kg)
- Can be operated with battery or AC power (optional)
- Mini USB port for easy data output and software updates (optional)
- USB connection allows you to easily check saved measurement results on your PC
- Multi-wavelength absorbance measurement possible
- A variety of cell adapters are included as standard (4 types of cell adapters)
