Description
Built for industrial professionals working in hydrogen-rich environments, the Dräger Pac® 8500 (8328262) offers hydrogen-compensated carbon monoxide (CO H₂-CP) detection with optimized Canadian alarm thresholds. Designed to eliminate the risk of false-positive CO alarms due to hydrogen interference, this robust personal gas detector ensures accuracy in environments like refineries, steel production, and chemical processing.
Featuring a rugged, IP68-rated housing, intuitive word-free display, and 360° alarm notification system, the Pac® 8500 delivers safety and performance in the most demanding conditions. Compatible with Dräger X-dock® calibration and bump testing systems, the device is ideal for long-term field use with integrated data logging and configurable exposure limits.
Key Features
Hydrogen-compensated CO sensor (CO H₂-CP) – Provides accurate carbon monoxide readings in the presence of hydrogen gas.
Pre-configured for Canadian standards – Alarm thresholds set to 25 ppm (A1) and 50 ppm (A2).
360° alarm system – Bright visual LEDs, 90 dB audible alerts, and vibration for maximum awareness.
High-contrast LCD display – Word-free design for universal understanding; displays real-time concentration, units, battery status, and alerts.
Replaceable membrane filter – Protects internal sensors from dust and splashes to ensure consistent performance.
Data and event logging – Tracks gas exposure events and alarm conditions for compliance and safety audits.
Compact and lightweight – Designed for everyday use in the field with rugged construction.
Compatible with Dräger X-dock® – Simplifies bump testing and calibration for fleet management.
Color-coded housing – Clearly identifies gas sensor type to prevent mix-ups.
Intended Use
This Dräger Pac® 8500 model is specifically built for applications where carbon monoxide and hydrogen are present together, including:
Petroleum refining
Steel and metal manufacturing
Chemical processing
Battery rooms and fuel cell maintenance
Wastewater treatment plants
Confined space entry programs
