PAC 8500 Gas Detector


Dräger PAC 8500

The Dräger Pac® 8500 single-sensor 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: H2S with CO, O2 with CO, or H2S with O2.

The Dräger Pac 8500 series offers the following sensor combinations: hydrogen sulfide with carbon monoxide, oxygen with carbon monoxide, or 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.

You can count on the Dräger Pac 8500 to give you reliable, precise readings at any time even under extreme conditions. Our powerful sensors with a low t90 response time ensure quick reactions. In addition to the standard alarms, you 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. The data can be loaded on a PC via an interface and processed further there.

?If the Dräger Pac 8500 measures hazardous gas concentrations, it sets off an audible, visual and perceptible 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. 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 they have been 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.
