Pac 8500 CO-H2 CP (CA) | Draeger

The Dräger PAC 8500 CO-H2 CP (CA) is a single-gas personal gas detector designed specifically for the detection of carbon monoxide (CO) and hydrogen (H2) gases in industrial environments. This device is equipped with a CO/H2-compensated sensor, which eliminates the cross-sensitivity issues typically associated with hydrogen exposure when monitoring carbon monoxide levels. The PAC 8500 is California-compliant (CA), meaning it meets the specific regulatory standards set forth by the state of California for gas detectors, including those related to environmental safety and performance.

Key Features:

1. CO/H2-Compensated Sensor:

   • The PAC 8500 is equipped with an advanced CO/H2-compensated sensor. This special sensor is designed to eliminate the cross-sensitivity typically caused by hydrogen when detecting carbon monoxide. In many industrial environments, the presence of hydrogen can interfere with the accurate detection of carbon monoxide, but with the PAC 8500’s compensatory technology, this issue is effectively addressed.

   • This makes the PAC 8500 ideal for hydrogen-rich environments (such as refineries, chemical plants, and hydrogen production facilities) where both gases might be present.

2. Single-Gas Detection:

   • The Dräger PAC 8500 is a single-gas detector, focused solely on detecting carbon monoxide (CO) in the air. This makes it highly specialized for environments where CO detection is critical, such as in confined spaces, manufacturing, and facilities dealing with combustion processes.

   • While the PAC 8500 detects only CO, its compensated sensor ensures accurate readings even in the presence of hydrogen.

3. California Compliant:

   • The California-compliant (CA) designation ensures that the PAC 8500 meets the stringent California state regulations for air quality monitoring and hazardous gas detection. California’s environmental standards are among the most stringent in the U.S., meaning the PAC 8500 meets a high standard of safety and reliability for workplace use.

   • This compliance makes the PAC 8500 particularly valuable for businesses operating in California or those looking to meet high safety standards.

4. Compact, Robust, and Lightweight:

   • The PAC 8500 is designed for personal use and is compact and lightweight, making it easy for workers to carry it throughout their shifts.

   • The device is small enough to fit in a worker's pocket, but its robust design ensures that it can withstand the rough conditions often found in industrial settings.

5. Long Battery Life:

   • The PAC 8500 is equipped with a long-lasting rechargeable battery that ensures reliable operation over extended periods of use. It offers up to 2 years of continuous service, which minimizes downtime and maintenance costs.

   • The battery’s life depends on environmental factors and usage, but the device is designed for reliability during long work shifts.

6. Visual, Audible, and Vibrating Alarms:

   • The PAC 8500 features multiple alarm types, including visual (flashing LED), audible (loud alarm), and vibrating alerts, which activate when CO levels exceed the pre-set threshold.

   • These alarms are essential for alerting the worker to the presence of dangerous CO concentrations in the environment and ensuring a rapid response.

7. Clear LCD Display:

   • The device has an easy-to-read LCD screen that shows real-time gas concentration readings (in ppm). This display is backlit for visibility in low-light conditions and ensures that workers can quickly assess the gas concentration levels.

   • The display also shows the battery status, alarm thresholds, and other important data.

8. Ease of Use:

   • The PAC 8500 is designed to be user-friendly, with one-button operation for turning on/off and operating the device.

   • Simple and intuitive controls minimize the learning curve, allowing workers to start using the device with minimal training.

9. Durable Construction:

   • Built to withstand harsh environments, the PAC 8500 has a rugged design that is shock-resistant and water-resistant (IP68 rated).

   • Its durability ensures reliable performance even in challenging conditions like dusty environments, wet areas, or extreme temperatures.

10. Maintenance and Calibration:

    • Routine calibration of the device is made easy, with options for manual calibration or using Dräger’s X-dock calibration station.

    • Automatic calibration ensures accuracy and reliability in gas detection, with the device notifying the user when a calibration is due.
