The gas warning device Pac 7000 SO2 measures the concentration of sulfur dioxide precisely and warns of dangerous gas concentrations.

  • Single gas measuring device with powerful XXS sensor technology and fast sensor response times
  • Personalized measurement
  • Instant acoustic and visual alarm with vibration
  • Standard measuring range: 0 to 100 ppm SO2 (sulfur dioxide), A1/A2 alarm thresholds: 0.5/1 ppm
  • Designed for very long lifespan
  • Meets dust and water protection requirements with IP 68
  • Secure attachment with tightly closing crocodile clip

Conduct the required functional tests before each use with the Dräger test and calibration stations and the associated test gases. Basis for the functional tests are the information sheets T021 / T023 (DGUV Information 213-056 and DGUV Information 213-057). Further information can be found here.

If you wish to configure individual alarm thresholds, please specify the alarm thresholds in the comment field at the end of the ordering process.
