Loveland, Colorado, September, 2008 — Hach introduces chlorine and iron testing parameters for its total laboratory analysis system featuring TNTplus chemistries, methods and DR2800/5000 Series Spectrophotometers. Ideal for drinking water and industrial water facilities, both chlorine and iron TNTplus parameters are USEPA equivalent and can be used for reporting. Chlorine TNTplus allows users to sequentially determine free and total chlorine in one vial. TNTplus products work exclusively with Hach’s DR2800/5000 Series Spectrophotometers to increase productivity and minimize analysis errors automatically. With TNTplus, operators gain the added benefits of: Barcoded vials — save time and money • Automatic reading of the barcode, method detection and display of measurement results — simply insert the vial. • Accurate data — the spectrophotometer rotates the TNTplus vial, averages 10 measurements, and rejects outliers. Dirty, scratched, or flawed glassware, including fingerprints, are no longer issues. • Hassle-free operation — no blank is required for most parameters. Self-contained packaging — reagents inside sealed cap • Reduced exposure to chemicals — no need to open pillows or clean glassware.
