Miniature, lightweight Dräger Pac Series single-gas detectors are designed for easy personal detection of hazardous gas levels. Pac Series detectors are specially designed to allow gas to enter the sensor from several directions to reduce the possibility of blocked airflow to the sensor. Three different Pac models are available to meet the needs of different industrial users and applications. The Pac 7000 is an advanced indefinite-life single-gas detector with datalogger and advanced alarm and display options. The new Pac 5500 features a renewable lifespan with replaceable battery, sensor, and filter. The Pac 3500 offers the same powerful detection as the Pac 5500 but with a lifespan of two years (non-replaceable sensor). The Pac 5500 and 3500 feature an event logger for up to 60 events. All Pac Series detectors are available for oxygen, hydrogen sulfide, or carbon monoxide. The Pac 7000 is available for seven additional gases.
