Abstract
A hood assembly for opacity monitoring equipment including an opacity monitor fixedly secured to an outside surface of a smokestack or chimney includes a hood for protectably covering the opacity monitor and associated guide. The guide is connectable to the monitor in a stationary relationship therewith and cooperates with the hood for guiding bodily displacement of the hood relative to the monitor along a substantially vertical path between a lowered condition at which the monitor is substantially covered by the hood and an elevated condition at which the monitor is accessible.

A hood assembly for opacity monitoring equipment including an opacity monitor fixedly secured to an outside surface of a smokestack or the like comprising:
- hood means for substantially covering the front, top and sides of an opacity monitor and
- guide means connectable to the monitor in a stationary relationship therewith and cooperating with said hood means for guiding bodily displacement of said hood means relative to the monitor along a substantially vertical path from a lowered condition at which the monitor is substantially covered by said hood means and an elevated condition at which the monitor is accessible.
In combination:
- opacity monitoring equipment including an opacity monitor fixedly secured to an outside surface of a smokestack and
- a hood assembly including
- (a) hood means for protectably covering the front, top and sides of said opacity monitor and
- (b) guide means attached to said monitor in a stationary relationship therewith and cooperating with said hood means for guiding bodily displacement of said hood means relative to said monitor along a substantially vertical path from the lowered condition at which said monitor is substantially covered by said hood means and an elevated condition at which said monitor is accessible.
