The OnGuard family of air quality monitors is designed to be wall-mounted in libraries, museums and archives. With an OnGuard monitor, you can determine in real-time the reactivity of the environment and take immediate action to protect priceless artifacts from pollutant gases.

The OnGuard earned the coveted R&D 100 Award in 1992 and has become a "must-have" air quality monitor in facilities where environmental conditions can be damaging to documents, art, and artifacts.
