The Dräger Pac 3500 is the ideal personal protective gas detection alarm for accurate measurement and easy operation. This instrument can detect ambient air in rapid and continuous usecarbon monoxide，hydrogen sulfideoroxygenand timely alarm, with a service life of 2 years, designed for industrial safety applications.
Compact and rugged
The Dräger Pac 3500 has a layer of rubber on the outside, which is resistant to impact and corrosion, and has an Ingress protection of IP66/67, which allows it to be used even in the presence of water. A belt clip on the back allows the instrument to be pinned to the user's body. Safety is placed first The position of the sensor is specially designed to allow gas to enter from the top and front of the instrument at the same time, and the device is placed in a pocket or the air inlet is accidentally obscured without hindering continuous gas detection.
Micro sensor technology
Equipped with the latest miniature Dräger X X S sensor technology, the Dräger Pac 3500 is tailored for personal portable inspection. The sensor is durable and pressure-compensated, and can accurately detect CO, H2S and O2. The Dräger Pac 3500 sensor has very low drift and can be used for 2 years without calibration.
High definition display
The large LCD display is clear and bright, showing both the gas concentration and the unit of measurement. As an option, the instrument can also be set to only the gas type on the screen. The gas concentration is displayed on the screen only when the alarm level is reached. To avoid language barriers, the concentration display does not use any words. The display background light is on for easy readings in dark environments.
In addition, the yellow label (hydrogen sulfide) and blue (oxygen) ensures fast identification of the instrument from a distance.
Warnings and alarms
The Dräger Pac 3500 not only features an audible vibration alarm, but also provides a 360° visual alarm at the top and bottom of the instrument. The alarm limit values can be set by the user according to corporate and local standards via Dräger software.
Data storage
The Dräger Pac 3500 can record 60 events including date and time, and can be matched to the infrared interface and data cable connection to the computer. Typical events such as on/off, gas and battery alarms, pattern errors, configuration changes, fresh air calibration and functional tests can all be downloaded, printed and stored.
