Water plant laboratories seek to balance speed and accuracy in sampletesting — accuracy of course being paramount. The optimum testing protocols are fast and accurate as well as simple to follow, even for staff members who are not necessarily chemists.
The marriage of those characteristics is the goal behind a newly introduced set of vial chemistries and a new spectrophotometer from Hach Company. The TNTplus chemistry system uses barcoded vials in packaging that is color-coded for ease in recognizing parameters and ranges.
The DR 3900 spectrophotometer is designed to provide consistently accurate results using simple, step-by-step, on-screen instructions for each test. It
