MSA PrimaX® IR+ — infrared combustible gas detector with local and remote mounting
The PrimaX IR+ is an advanced infrared detector for detecting combustible gases in the 0-100% LEL range, available both as a locally mounted sensor and with remote sensor mounting. A patented dual infrared source design and SIL 2 compliance ensure uninterrupted, reliable measurement even if one source fails. Heated optics and a patented sensor guard minimize the risk of interference from rain, fog, dust or contamination, while HART protocol support simplifies configuration, calibration and diagnostics.

Frequently asked questions (FAQ)
How does the PrimaX IR+ differ from the standard PrimaX IR?
The PrimaX IR+ additionally offers local and remote sensor mounting, a segmented LED display, configurable alarm/fault relays and an option of a stainless steel or aluminum housing.
What measuring range does the PrimaX IR+ have?
The detector measures combustible gas concentration in the range of 0-100% of the lower explosive limit (LEL).
How does the PrimaX IR+ handle harsh weather conditions?
Heated optics and a patented sensor guard minimize the risk of interference caused by rain, fog, dust and contamination, while the dual IR source ensures continuity of measurement even if one of them fails.
