OPSIS - Calibration Equipment for Emissions Monitoring and Process Control
Calibration is needed to show that the monitoring results agree with reality. If they do not, you can adjust the results of the instruments. There are several different products for calibrating the OPSIS monitoring system. Most often, the starting point is a calibration bench model CB100. It is used together with an emitter/receiver set (ER060) so that a monitoring path is formed along the bench.
Calibration is done by inserting one or more cells with transparent windows into the light path. Calibration gas of known concentration flows through the cells. Varying cell lengths or combinations of different cells make it possible to select different calibration points with one and the same gas source. Zero point calibration is done by measurements in the calibration bench without cells.
Gas cylinders with traceable and certified gas concentrations are usually used as a gas source. However, some gases cannot be supplied in cylinders, for example total mercury. In that case, an OPSIS LC500 gas calibrator is used to generate a known concentration.
