Opsis AR600 series

Multi-component analysers for CEMS & process control

The Opsis AR600 series of analysers is the central unit of an Opsis Continuous Emissions Monitoring System. It utilises differential optical absorption spectroscopy (DOAS) in accordance with Beer Lambert’s Law to measure a wide range of gaseous parameters in the UV and IR wavelength. The analyser receives light from one or more light paths via a fibre optic cable and provides data for presentation through Opsis software.

It features a high-performance spectrometer where received light is converted into digital signals and analysed by the built-in computer. The computer software includes the spectrographic ‘fingerprints’ of a number of user-specified compounds. The system detects and measures these compounds through the depletions they cause in the spectrum of received light. It then refines results by calculating margins of error for each value and by noting the proportion of transmitted light received by the analyser. This allows both data and system verification.

Acoem Australasia (Ecotech Pty Ltd) is the official representative and distributor of Opsis products in Australia and New Zealand.

Features

Can be updated or expanded at any time and is prepared for the addition of automatic calibration equipment. Updating to monitor additional gases usually involves a simple software upgrade

Includes interfaces as standard

For a multiplexer (multiple light paths) and for a data logger (when integrating external signals from meteorological sensors)

Ambient temperature

+15 °C to +25 °C (+60 °F to +80 °F)

Multiple communication ports for data transfer

Via modem, LAN or internet, using optional communication devices
