Hach Spectral Photometer model DR3900 with RFID* (Radio-Frequncy Identification) Technology. This photometer is pre-programmed with all HACH LANGE analysis methods, for waste water, drinking water and cooling/boiler water. The in-built technology helps to reduce errors and gives full traceability. Not only can the operator trace samples back to their locations but also the sample taker, date and time which are all saved on an RFID* tag on the sample bottle. This data can then be transferred to the laboratory in seconds using RFID in the DR3900.

Product contents:

Adapter “A” for 1” round and ACCUVAC/1cm rectangular cells, basic handbook, CD with handbook and work processes in 5 languages (GB, D, F, I, E) in PDF format, EU power pack, user RFID* tag.

Programming of methods into a spectrophotometer has never been so easy. Simply hold the cuvette test box in front of the RFID* module, wait for the signal tone and it‘s done. Measurement begins straight away with accurate evaluation data for an accurate result. Data transfer is simple via USB or Ethernet connection.

The same applies for software updates, the DR3900 can install the most up-to-date device software from the Hach website via Ethernet, so your photometer always has the latest update.

QA procedures can now be easily defined and documented within the instrument without additional software using Aqua . Current batch certificates (for the purpose of GMP/GLP results documentation) can be found on the RFID* tag on the cuvette box. Thanks to this technology, all batch-specific information can be retrieved immediately on the DR3900 and printed out.

Alignment of laboratory and process analysis

The operator can compare the process result with the laboratory reference value in the photometer via the LINK2SC connection between the SC controller and the DR3900. Data can be exchanged via Ethernet bi-directionally, eg, matrix corrections from process probes can be sent directly from the laboratory.

Using IBR increases the reliability of the measurement values, lot number and expiry date information is now included on the 2D barcode. This additional information is transferred to the instrument and documented with the measurement value.
