Description
The Gas-Pro is Crowcon's confined-space multi-gas detector for up to five gases, in a compact, rugged housing with a top-mount display.
Diffusion or pumped (pump runs from the flow plate), with options for infrared (IR) flammable/CO2 and PID VOC sensing. Standard configurations are listed here — the full Gas-Pro configurator range (1,800+ factory gas combinations) is available on request.
Common Applications:
Confined Space Entry • Personal Monitoring • Oil & Gas • Chemical • Wastewater • Steel • Marine

- Portable detector monitoring up to 5 gases in a compact, rugged housing
- Optional internal pump, activated by the flow plate, for pre-entry testing — switch between pumped and diffusion modes
- Top-mount display for easy at-a-glance reading
- Simple single-button operation, usable while wearing gloves
- Specific Pre-Entry Check (PEC) mode with automatic fail-safe flow plate recognition
- IR sensor option for CO2 and flammable gases — poisoning-resistant and works in low-oxygen atmospheres; PID option for VOCs
- Bump and calibration reminders for compliance, with I-Test and Q-Test bump/calibration solutions
- Multiple languages
