Mounting The Plastic-Housing Instrument
The plastic-housing MeshGuard LEL IR or MeshGuard CO2 IR is permanently mounted to a solid surface
by first securing it in its steel enclosure (a screw through the back mates with the instrument) and then
securing the enclosure to a solid surface such as a wall or the metal mounting plate.
Front, side, and rear views of the steel enclosure show how the instrument is secured for
mounting.
