Thermo Scientific AQ3140 Orion AQUAfast COD Colorimeter

Thermo Scientific AQ3140 Orion AQUAfast COD Colorimeter

Durable Construction, designed for accuracy

Designed to provide accurate measurements, the Thermo Scientific Orion AQUAfast AQ3140 COD colorimeter makes it ideal for laboratory testing of chemical oxygen demand (COD).

The Thermo Scientific™ Orion™ AQUAfast™ AQ3140 COD colorimeter is a single parameter instrument for determining chemical oxygen demand in water.

The AQUAfast AQ3140 COD colorimeter and COD reagents measures COD in the range of 0 – 15000 mg/L through dichromate method that estimates the theoretical oxygen demand, i.e. the amount of oxygen consumed in total chemical oxidation of the organic constituents present in the water. The colorimeter is designed to give accurate results that are highly reproducible. AQ3140 measures the COD concentration by photometric detection employing a linear relationship between absorbance and concentration.

The AQUAfast AQ3140 colorimeter offers a number of features designed to improve user experience, including two LED light sources for long-term stability.
