Gas detector 3350

oxygenindustrialfor ambient air

The Model 3350 accurately measures the concentration of oxygen in control rooms, closed atmospheres, critical breathing circuits and other applications that require the fail-safe monitoring of breathable, ambient air. It is a microprocessor-based oxygen alarm monitor for real-time measurement of the oxygen content of the atmosphere surrounding the sensor as well as shoulders the burden of personal safety with the quality and reliability offered by the Teledyne name. Advantages Dual Oxygen Analyzers The alarm set-points provide an operational band that covers all acceptable oxygen concentrations. If the oxygen level at the sensor crosses the adjusted set-point of one of the alarms, that alarm will cause the switching of relay contacts. The standard factory setting of the two alarms provides a CAUTION alarm at 20% oxygen and a DANGER alarm at 19.5% oxygen. To cover special situations, a limited amount of adjustment is possible. Both alarm set-points are factory set (internal) to prevent tampering or resetting by unauthorized personnel. When insufficient oxygen concentration triggers either alarm, a red panel light and an audible annunciator are energized. The alarms remain energized until the oxygen concentration has been elevated above the trigger point. Battery Backed Standby Power An optional battery backed standby power configuration is offered for potential power failure or “brown out” conditions. With this feature, power outages will not interfere with a proper working alarm. The standby power source uses a rechargeable lead acid battery.
