Pac 8500 Single or Dual Gas Monitor


​The Dräger Pac 8500 single-gas detection device is a reliable and precise instrument even under the toughest of conditions. The detector can be equipped with a hydrogen-compensated CO sensor or a Dräger dual sensor. The dual sensors provide the option of measuring two gases at once: either H2S with CO or O2 with CO.


Pac 8500 Single or Dual Gas Monitor

The Pac 8500 Series includes

  • CO H2P gas detector 8327617
  • O2 gas detector / CO gas detector 8328265
  • H2S gas detector/ CO gas detector 8328263


Strong performance for maximum safety

Emergency responders can count on the Dräger Pac 8500 to give them reliable, precise readings at any time even under extreme conditions. Our powerful sensors with a low t-90 response time ensure quick reactions. In addition to the standard alarms, users can define extra alarm thresholds for TLV* and STEL*.

The Pac 8500 also provides a data and event logger for logging concentrations and events along with the date and time. Users can load the data onto a PC via an interface and process it further there.

* TLV = Threshold Limit Values, STEL = Short Term Exposure Limit

Two gas detection in a single-gas device

The Dräger Pac 8500 series offers the following sensor combinations: hydrogen sulfide with carbon monoxide or oxygen with carbon monoxide. Dual sensors enable detection of even low concentrations – all in one and the same handy device. Measuring two gases at the same time reduces downtime as well. Users can take vol.% measurements of oxygen and ppm measurements of carbon monoxide simultaneously using just one gas detector.

Measurement of carbon monoxide with significantly reduced cross sensitivity

In industries where responders must measure carbon monoxide with hydrogen as a background gas, cross sensitivity may falsify the measured value for carbon monoxide. The special hydrogen-compensated CO sensor from Dräger significantly reduces this cross sensitivity to hydrogen in the display of carbon monoxide. This new feature can eliminate the need to carry two different detectors.

Robust design – even for the toughest conditions

Users can easily handle the Pac 8500 even in extreme conditions. The sensors can tolerate air pressures between 700 and 1,300 mbar. 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.

Easy handling thanks to clear user guidance

The D-Light indicates whether functionality of the device has been tested and if it is ready to use. The housing is also designed with the user’s safety in mind: each sensor variant of the Dräger Pac 8500 features clearly visible color coding, thereby minimizing the chance of mistakes.

User-friendly display with all important information

The large display is word-free and clearly indicates the respective gas concentration. It also displays other important information, such as the unit of concentration and battery capacity. The bright backlighting ensures that all values are clearly legible in the dark.
