The SG700 Stack Gas Analyzer consists of a non-dispersive infrared gas analyzer using a highly sensitive and stable double beam system and a zirconia or paramagnetic oxygen analyzer. It can simultaneously measure up to 5 components: NOx, SO
2, CO
2, CO, and O
2.
The use of interference compensation in the analyzing section virtually eliminates the effects of interference from other components. The SG700 features many functions including autocalibration, conversion to O
2-based values, averaging, and high/low alarms. It is used for measuring and monitoring emissions from various types of boilers and waste incinerators.
