Catalytic Bead DrägerSensor® PR NPT DQ Sensor for Fixed Gas Detectors

• Detects flammable gases and vapours
• Due to the double-detector compensation method, the catalytic sensor is particularly long-term stable
• The wire mesh at the gas inlet serves as a flame barrier, so it ensures explosion protection at the same time as a short response time
• Flame-proof stainless steel housing
• UL Approval
