3M Spyglass - Open Path Combustible Gas Detector

The Spyglass system detects hydrocarbon gases by analyzing the absorption of radiation caused by gases in the atmosphere and comparing it to background atmospheric absorption. This is accomplished between a pair of units: a Flash Source and a Detector that can monitor a distance of up to 200 meters. Spyglass Gas Detectors are robustly designed and can handle the toughest environments: 316L stainless steel housings that meet IP66/IP68 and NEMA 250 6P egress standards; circuit boards epoxy coated for protection; MIL-C-810C testing for humidity, salt, fog, vibration, mechanical shock and temperature extremes; and SIL-2 approval per IEC61508 is a final statement in reliability.
