Dräger Pac 8500

Strong Performance and Maximum Safety
You can count on the Dräger Pac 8500 to give you reliable, precise readings at any time even in extreme conditions. The powerful sensors with a low t-90 response time ensure quick reactions. In addition to the standard alarms, you can define extra alarm thresholds for TLV®* and STEL*.

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

Dual Gas Detection in a Single-Gas Device
The Dräger Pac 8500 series offers the following sensor combinations:
•    Hydrogen Sulfide with Carbon Monoxide
•    Oxygen with Carbon Monoxide
•    Hydrogen Sulfide with Oxygen

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. You can take vol.% measurements of oxygen and ppm measurements of carbon monoxide simultaneously using just one gas detector.

Carbon Monoxide Measurement Reduced Cross Sensitivity
In industries where carbon monoxide needs to be measured with hydrogen as a background gas, the measured value for carbon monoxide may be falsified by cross sensitivity. Thanks to the special hydrogen-compensated CO sensor (CO-H2 CP) from Dräger, this cross sensitivity to hydrogen is significantly reduced in the display of carbon monoxide. This new feature can eliminate the need to carry two different detectors.

Robust Design for Tough Conditions
The Pac 8500 can easily handle 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 by the IP68 standard rating.

Easy Handling and Clear User Guidance
The D-Light indicates whether the functionality of the device has been tested and that it is ready to use. The housing is also designed with your safety in mind: each sensor variant of the Dräger Pac 8500 features clear, easily visible color coding, thereby minimizing the chance of using the incorrect detector.

The large display clearly indicates the respective gas concentration in the unit of concentration as well as the battery capacity. The bright backlighting ensures that all values can be clearly read in the dark.

360° Alarm
If the Dräger Pac 8500 measures hazardous gas concentrations, 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 signal reaches a volume of 90 dB and the display can show the peak concentration measured at any given moment. Earlier alarms registered can also be retrieved at a later time, even if acknowledged.

The Pac 8500 with oxygen sensor has two additional alarm thresholds in addition to the standard alarm threshold settings. This provides an additional level of safety as a pre-alarm, in addition to the main alarm, can be set for both oxygen enriched and oxygen deficient atmospheres.

Data & Event Logger
The Pac 8500 logs concentrations and events along with date and time. The data can be downloaded to a PC via an interface and processed for future use.

Economical Operational Costs
All of the versions of the Dräger Pac 8500 are equipped with extremely durable Dräger sensors and a powerful battery that does not require changing every day.

Fast Function Test Saves Time & Money
Function tests and calibrations can be carried out especially efficiently in the Dräger X-dock® calibration station. The automatic bump tests in the X-dock are a cost-efficient and convenient solution thanks to short test duration and the extremely low test gas consumption. The Pac 8500 is simply placed in the bump test station and automatically selects the correct setting.
