The SL1000 portable parallel analyzer (PPA) from Hach is designed to quickly and consistently test multiple parameters in drinking water systems. The analyzer can simultaneously test four colorimetric and two probe-based parameters by inserting the appropriate Chemkeys into the sample for one to two seconds. Status bars on the analyzer display time remaining until test results are complete.“Instead of having to run separate tests for chlorine, monochloramine, free ammonia and nitrite, you can run all of those at the same time, taking the testing time in many instances down from about 20 minutes to eight minutes,” says Ursula Jessee, Hach
