Spectrophotometer DR3900

The Hach DR3900 spectrophotometer, used for COD (Chemical Oxygen Demand) analysis

A Chemical Oxygen Demand (COD) analyser in a lab is used to measure the amount of oxygen required to chemically oxidise organic and inorganic compounds in a water sample.
This measurement helps assess the level of organic pollutants and the potential impact of wastewater on receiving waters.
COD analysis is crucial for monitoring wastewater treatment plant efficiency, ensuring compliance with environmental regulations, and assessing overall water quality.

Here’s a more detailed breakdown:

Spectrophotometer DR3900

The DR3900 is a benchtop visible spectrum (320 – 1100 nm), split beam spectrophotometer with over 220 pre-programmed methods optimized for laboratory water analysis.
With your daily routine of water analysis in mind, the DR3900 spectrophotometer is optimized for safe processes and accurate results.

The DR3900 is designed to deliver accurate results quickly with Hach’s innovative TNTplus and LCK reagents for fast preparation and easy execution.
In fact, it automatically recognizes our Hach reagents, so there is no need to enter method numbers

Guided Procedures
The DR3900 simplifies water analysis by with step-by-step guides which take users through testing procedures. This helps ensure consistent and accurate results.

RFID Technology
Featuring state-of-the-art Radio Frequency Identification (RFID) technology* allows for hands-free calibration updates, as it automatically recognizes the lot, expiration and calibration curves associated with each Hach chemistry sample. It also allows for traceability for each measurement.

Claros Enabled
This instrument connects to Claros, Hach’s innovative Water Intelligence System, enabling you to seamlessly connect and manage instruments, data, and process – anywhere, anytime. The result is greater confidence in your data and improved efficiency in your operations.
