• Specifically designed to work with trusted Hach reagents
• Last method recall and "Favorites" make your most used methods easy to find

Using proven Hach technology, the DR 1900 yields consistently accurate results using a familiar testing format. This compact unit is packed with features, including a large backlit display that shows the concentration, parameter selected, wavelength and program number, along with time, date, user ID and sample ID. A bar graph displays the analytical range or the method selected. Under range and over range warnings help to avoid using data that's out of the analytical range of the instrument.

This flexible meter is preprogrammed with over 220 of the most commonly tested methods, and accepts sample cells of many sizes and shapes. If you need to do a test that's not already in the meter, the easy-to-use interface helps you create up to 50 of your own test methods between 340 and 800 nm. Store up to 500 data sets and download them in .csv format for import into a spreadsheet with optional USB/power module. Meter provides step-by-step instructions when connected to a PC.

Includes: four sample chamber vial adapters, two 1" square sample cells (matched pair), water analysis handbook (CD), dust cover, four AA batteries and manual. 1-year warranty.

Note: TNTplus compatible, but without barcode identification, tenfold measurement and outlier elimination.
