Features:

Compact benchtop VIS spectrophotometer with RFID technology for reliable and traceable measurement results of routine analysis and user applications. This system is designed to deliver accurate results by supporting the operator from sampling to sample preparation, sample analysis and documentation.

By means of RFID technology you can trace your samples completely back to the sampling point. Lot number and expiry date information of the TNTPlus tests are logged thanks to the 2D barcode. The RFID module reads out and displays all batch specific information from the test box. The batch certificate can be printed out immediately via the spectrophotometer.
