Select a gas type and safety standard to get detection parameters.

🔬 Sensor Technologies

Catalytic Bead: combustible gases (%LEL)
Electrochemical: CO, H₂S, O₂, toxic gases
NDIR (Infrared): CO₂, CH₄, hydrocarbons
PID: VOCs, low-ppm organics
Semiconductor: general purpose, low cost

⚠️ Confined Space Rules

Test atmosphere before entry (OSHA 1910.146)
Monitor O₂, combustibles, and toxics simultaneously
Continuous monitoring required during occupancy
Bump test detector before each use

📋 Key Standards

OSHA 1910.146 IEC 60079-29 EN 50271 GBZ 2.1 ATEX Directive

🔄 Maintenance

Bump test: before each use (portable)
Full calibration: every 6 months
Sensor replacement: per manufacturer schedule
Fixed detectors: annual certification
