Spectrophotometer with RFID Technology

June 26, 2012

Hach Company’s DR 6000™ UV-Vis spectrophotometer is equipped with RFID technology, integrated QA software and more than 250 testing methods and guided procedures. The DR 6000 spectrophotometer provides reliable and traceable results. It is programmed to take absorbance readings of a single sample at different wavelengths or over a specific period of time, and allows high speed wavelength scanning across the UV and visible spectrum. When the DR 6000 is paired with Hach’s TNTplus® reagent vials, it detects and alerts users to expired reagents, ensuring chemistries are used within their shelf lives. In cases where changes to a stored program are required to use a new lot of chemistry, it prompts the user to perform the update. The RFID technology allows the DR 6000 to update the program’s calibration factors automatically when the TNTplus reagent box is placed near the instrument. Results are analyzed and outliers — caused by scratched, flawed or dirty glassware — are eliminated. Other testing errors are eliminated by following the on-screen guided procedures, which are available for the most common of the 250 pre-programmed methods. With optional accessories allowing for high volume testing and integrated QA software for scheduling, documenting and interpreting quality control measurements, this instrument is optimized for a wide range of water testing needs.
