The Hach SL1000 consolidates tools and offers rapid, real-time results as well as tools for data logging in a single hand-held device. It allows personnel to run four colorimetric and two probe-based measurements at the same time using the same water sample without special preparation. To conduct a test, the user simply inserts the Chemkey reagents and probes into the device, which detects the Chemkey and probe types. The user then dips the Chemkeys into the sample cup and shortly thereafter the unit will display the reading for each test. 800/227-4224; www.hach.com
