Pac 8500 Dual Gas Monitor for Hydrogen Sulphide and Oxygen (H2S/O2)
The Pac 8500 H2S/O2 gas detector measures hydrogen sulfide and oxygen simultaneously and warns of dangerous gas concentrations
- 2-in-1 single gas detector for personal measurement
- Sensor combination: hydrogen sulfide and oxygen
- four alarm thresholds for O2: 19.0%; 19.5%; 22.5% and 23.0%; alarm thresholds H2S: A1 = 5, A2 = 10 ppm
- Clearly visible 360° alarm, acoustic and optical
- The gas detector features powerful XXS sensor technology with high reaction speed
- Storage of concentrations and results with date and time
Perform mandatory function tests before each use with Dräger test and calibration stations and associated test gases. The basis for the function tests are the information sheets T021 / T023 (DGUV Information 213-056 or DGUV Information 213-057). Further information can be found here.
If you want a custom alarm threshold configuration, please specify the alarm thresholds at the end of the ordering process in the comment field.

Relevant Cross-sensitivities - Dräger Sensor XXS O2/H2S
The values indicated in the table are reference values and apply to new sensors. The indicated values may vary by ±30%. The sensor may also be sensitive to other gases (data available upon request from Dräger). Gas mixtures may be displayed as a sum. Gases with negative sensitivity may negate a positive display of O2 or H2S. It should be verified if gas mixtures are present.
