The Draeger Pac 6500 Gas Detectors are your reliable companion under tough conditions. The personal single gas detection device measures Carbon Monoxide, Hydrogen Sulfide, Sulfur Dioxide or Oxygen quickly and precisely. Quick sensor response times and a replaceable battery also ensure safety.

The Pac 6500 features powerful sensors with a very low T-90 response time to ensure quick reactions. The Pac 6500 is versatile thanks to its wide measurement range. For example the CO sensor measures concentrations from 1 to 1,999 ppm. The D-Light indicates whether the functionality of the device has been tested and that it is ready to use. Each sensor variant of the Draeger Pac 6500 features a clearly visible color coding.

The Pac 6500 is easily handled in even extreme conditions: depending on the sensor, temperature from -40°C to 55°C. A membrane filter protects the sensor from foreign matter such as dust and liquids. The shock-proof, chemical resistant housing meets the requirements specified in the IP68 standard rating.

The large display clearly indicates the respective gas concentration. Other important information, such as remaining operating time and battery capacity is also displayed. The bright backlighting ensures clear reading of all values in the dark.

If the Draeger Pac 6500 measures hazardous gas concentration, it sets off an audible, visual and noticeable vibrating alarm. Two bright, flashing LEDs on the top and bottom of the device ensure that the alarm is easily visible from all sides. The acoustic alarm reaches a volume of 90 dB. The display can show the peak concentration measured at any given moment. Earlier alarms registered can also be retrieved at a later time. The Pac 6500 with oxygen sensor has two additional alarm thresholds in addition level of safety as a pre-alarm. In addition to the main alarm, can be set for both oxygen enriched and oxygen deficient atmospheres.

The Pac 6500 logs concentrations and events along with date and time. The data can be downloaded to a PC via an interface and processed further there.

All versions of the Pac 6500 are equipped with a powerful battery. Neither the sensor nor the battery need to be changed for the entire 2 year maintenance free service life of the units.
