WAT3800

The DR3900 is a benchtop visible spectrum (320 - 1100 nm), split beam spectrophotometer with over 220 pre-programmed methods optimised for laboratory water analysis. With your daily routine of water analysis in mind, the DR3900 spectrophotometer is optimised for safe processes and accurate results. Control-parameters like Ammonium, COD, Phosphate, Nitrate and many others are easy to perform. The handling of tests and spectrophotometer is well designed to avoid any errors in your water analysis. The new 2D barcode details the batch number and the expiry date of the reagents. During the measurement process the DR3900 immediately picks up all the information on the cuvette by using the IBR+ barcode reader. If the expiry date has already passed, an automatic warning will be issued. Method updates are also identified by the 2D barcode. The calibration data is incorporated in the RFID tag on the box for hands-free update with the RFID module.

Simple preparation - boxes and cuvettes are colour-coded for fast and easy parameter and range recognition, step-by-step illustrated test methods are printed on the box as quick reference or can be called up in the instrument menu
Use RFID technology to enable reliable communication with the sample taker and the samples
