The IR-741XP Sample Conditioner is for applications such as refineries and petroleum transfer stations, which require NEMA-7 (National Electrical Manufacturers Association) Class I, Div I hazardous areas compliance standards. Encompassing all the features of the standard IR-741, the IR-741XP boasts a temperature-controlled environment, low-flow alarm, and a NEMA-7 explosion-proof enclosure.

The IR-741XP rugged all-weather design will assure you of many years of trouble-free service while safeguarding your test equipment from maintenance inducing contaminants of your test site.

The IR-741XP features a built-in pump and a flow meter and provides the flow regulation required for accurate readings with any gas analyzer. The IR-741XP is pictured above with the IR-8400D Continuous Emissions Monitoring Gas Analyzer from Infrared Industries.

A filter removes particulates and moderate amounts of water. This conditioner features inputs for two sample points as well as zero gas and calibration gas connections. This instrument is available for either corrosive or non-corrosive service and is panel mounted.
