Description
The Dräger Pac® 8500 (8326366) is a compact, high-durability dual-gas detector designed for simultaneous monitoring of oxygen (O₂) and carbon monoxide (CO) in industrial and confined space environments. This model combines accurate detection of toxic gases with the ability to monitor life-supporting oxygen levels, making it ideal for emergency responders, confined space entrants, and industrial safety professionals.
Equipped with fast-responding DrägerSensor® XXS sensors, the Pac® 8500 delivers real-time gas concentration readings, while the rugged IP68-rated housing, 360° visual and audible alarms, and word-free display provide immediate and universal alerts in high-risk situations.
Key Features
Dual-sensor capability – Monitors both carbon monoxide (CO) and oxygen (O₂) in one compact device.
High-visibility 360° alarms – LED, 90 dB audible, and vibration alarms for immediate hazard awareness.
Backlit, word-free display – Shows real-time concentrations, units, battery status, and alarm conditions.
Rugged and durable – IP68-rated for water and dust resistance; suitable for extreme industrial environments.
Preset alarm thresholds – Configurable to short-term and long-term exposure limits for CO and O₂.
Event and data logging – Tracks gas exposure and alarms for compliance reporting and audits.
Replaceable filter membrane – Protects sensors from dust and splash, extending the detector’s lifespan.
X-dock® compatible – Supports Dräger's calibration and fleet maintenance systems.
Intended Use
The Dräger Pac® 8500 O₂/CO is ideal for professionals who need to monitor oxygen deficiency/enrichment and carbon monoxide exposure in environments such as:
Confined space entry (tanks, pits, vessels)
Mining and underground worksites
Oil & gas and petrochemical facilities
Steel production and welding zones
Hazardous material and emergency response teams
