Personnel safety is a primary issue in every industry, and no factor is more important than assuring an appropriate level of oxygen in an enclosed area.

Teledyne's Model 3350 measures the concentration of oxygen in control rooms, closed atmospheres, critical breathing circuits, and other applications that require fail-safe monitoring of breathable, ambient air.

Simple to use and maintain, the 3350 is a microprocessor based alarm monitor for real time measurement of the oxygen content of the atmosphere. Designed in consideration of OSHA specifications, the standard instrument is configured to run from an AC power source and is available with an optional DC battery backup.
