Dräger Pac® 6500 Single-Gas Detector – SO₂ (Sulfur Dioxide)

The Dräger Pac® 6500 is a rugged, personal single-gas detector designed to help protect workers from exposure to hazardous gases. This version is equipped with a sulfur dioxide (SO₂) sensor for monitoring potentially dangerous concentrations during industrial and other workplace activities.

Built to withstand demanding environments, the Pac 6500 combines durable construction with straightforward operation and clear visual feedback. Its large display provides real-time gas concentration readings, while bright backlighting makes information easy to read in low-light conditions.

When hazardous gas concentrations are detected, the device activates audible, visual, and vibrating alarms. Two flashing LEDs positioned on the top and bottom of the monitor provide 360-degree visibility, while the audible alarm reaches 90 dB.

The Dräger Pac 6500 also features a D-Light status indicator that communicates whether the device has been function-tested and is ready for use. Its data and event loggers record gas concentrations and events along with date and time information for subsequent analysis.

Routine functional testing and calibration help ensure portable gas detectors are operating as intended. The Dräger Pac 6500 is compatible with the Dräger X-dock® calibration station, which supports automated bump testing and calibration.

Dräger also offers a dedicated Bump Test Station for functional testing using a test gas cylinder. The device’s replaceable filter helps simplify maintenance and keep the monitor ready for continued use.

About Sulfur Dioxide (SO₂)

Sulfur dioxide is a hazardous gas that requires appropriate workplace monitoring where exposure may occur. The Dräger Pac 6500 SO₂ model provides dedicated single-gas detection to help workers identify potentially hazardous concentrations in their surrounding environment.

Select the appropriate gas detection equipment based on your workplace hazards, exposure risks, and applicable safety requirements.

What’s the difference between the Dräger Pac 6000 and the Pac 6500?

In short:

• Pac 6000: disposable, 2-year use, minimal maintenance
• Pac 6500: non-disposable, replaceable battery, longer-term use, TLV/STEL support

In a bit more detail, the main difference is lifecycle and operating concept:

• Pac 6000 is a disposable personal single-gas detector. Dräger describes it as providing safety for up to two years with virtually no maintenance required.
• Pac 6500 is a reliable non-disposable single-gas detector. Dräger describes it as having replaceable battery and economical operating costs.

Both devices are intended for personal air monitoring and can measure the same gases: CO, H2S, SO2, or O2. Both are built for tough conditions and have a robust housing with IP68 protection. The 6000 has a two-year operating life, from the time of initial activation. The 6500 has TLV/STEL support.

What is TLV and STEL?

These acronyms stand for Threshold Limit Value and Short Time Exposure Limit, and are occupational exposure limits. The 6500 offers TLV average exposure limit for 8 hours, and STEL for 15 Min. The 6000 does not incluse TLV/STEL support.
