Spectrophotometer
The Hach DR 3900 bench-top spectrophotometer has guided testing procedures and RFID technology for accurate water analysis; it eliminates false readings by taking 10 readings of a prepared sample from different angles and removing outliers. The unit automatically recognizes the lot, expiration and calibration curves associated with each TNTplus chemistry sample when a TNTplus box is placed next to the machine.
