Hach Company, a manufacturer and distributor of instruments used for testing water quality, has launched its DR 3900 spectrophotometer equipped RFID technology.
The RFID technology allows for hands-free calibration updates. When an operator places a RFID tagged TNTplus chemistry sample, used to test water quality, next to the machine, the DR 3900 automatically updates calibration factors. It also alerts users know if the sample is expired.
To eliminate sample mix-ups and provide better traceability, sample bottles with smart tags can also be easily tracked with the optional Hach RFID sample ID system. The combination of RFID tags at the sample location, on the bottle and with each operator allows traceability for each measurement.
Additionally, the DR 3900 was built to connect with any computer or water management system through 1 LAN and 3 USB ports. This allows users to store and share the data in a way that is best suited to their needs. ![[end]](/resources/bullet/rfidnews-4.gif)
