Product overview

An online differential UV analyzer with heated sampling and enhanced conditioning for demanding process gases.

Differential UV analysis for high-temperature and high-moisture samples

DOAS-3000 is an online differential ultraviolet gas analyzer designed for high-temperature, high-humidity or high-dust process samples. Typical applications include flue gas emissions, desulfurization and denitrification, boiler exhaust, VOC emissions and wastewater-pipeline monitoring.

Heated sample transport, dust filtration and two-stage condensation dehumidification condition the sample before analysis and help limit losses of water-soluble components. The automated system displays results locally and can transmit data to control systems or remote monitoring platforms.
