| The Hach DRELs (direct-reading environmental laboratories) constitute a line of 12 new portable laboratories. They are equipped with the Portable Datalogging DR/2010 Spectrophotometer and other features needed to run water-quality tests. Users can choose from 12 application-oriented configurations or customize a DREL based on individual testing requirements. The spectrophotometer is powered by batteries or line power. It includes preprogrammed calibrations for more than 120 common water-quality parameters and provides readout in concentration units, %T, or ABS units. With the data-logging feature, users can store up to 1,000 sample readings and later download to a computer or printer. Optional portable instruments for the DRELs include the EC10 Portable pH Meter, CO150 Conductivity meter, 2100P Portable Turbidimeter, and Digital Titrator. Five DRELs are available for specialized water-quality testing: Complete Water Quality Laboratory, Basic Water Quality Laboratory, Soil and Irrigation Laboratory, Aquaculture Laboratory, and Water Conditioning Laboratory.|
