The Hach DR3900 VIS Spectral Photometer uses RFID* technology allowing you to reduce errors. Samples can be traced back to the sample location. All the important information is saved on an RFID tag and can be transferred back to the laboratory in seconds. 

Standard features

  • Pre-programmed with all HACH LANGE analysis methods, for the analysis of waste water, drinking water and cooling/boiler water
  • Absorbance and transmission
  • Concentration for linear and nonlinear calibration curves

IBR+ increases the reliability of your 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.

Rapid data updates
Programming of methods into a spectrophotometer has never been so easy. Simply hold the cuvette test box in front of the DR 3900 RFID* module, wait for the signal tone and it‘s done. Measurement begins straight away with accurate evaluation data for an accurate result.

Quality assurance made easy with AQA+
QA procedures can now be easily defined and documented within the instrument without additional software. 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 RFID* technology, all batch-specific information can be retrieved immediately on the DR 3900 and printed out.

Alignment of laboratory and process analysis
You can compare your process result with the laboratory reference value in the photometer via the LINK2SC connection between the SC controller and the DR 3900. Data can be exchanged via Ethernet bi-directionally, eg, matrix corrections from process probes can be sent directly from the laboratory.

Data transfer is simple via USB or Ethernet
Transfer your measurement data easily via a USB stick or an Ethernet connection. The same applies for software updates. The DR 3900 can install the most up-to-date device software from our website via Ethernet, so your photometer always has the latest update.
