Description
Crowcon Gas-Pro IR is a personal multi-gas detector for hazardous industrial and offshore areas, using infrared sensing for reliable flammable and CO₂ monitoring.
Crowcon Gas-Pro IR is a compact personal multi-gas detector for industrial and offshore oil and gas environments, including confined spaces and other hazardous areas. It combines up to five sensors for toxic gases, flammable gases, oxygen, CO₂ and, where specified, VOCs into one rugged, lightweight instrument. Advanced infrared sensing maintains dependable flammable and CO₂ detection in low or zero oxygen conditions, while simple single-button operation, a clear top-mounted display and strong audible, visual and vibrating alarms support safe, consistent operation across long shifts.
AT A GLANCE
- Flexible five-gas platform: Combines flammable, toxic, oxygen, CO₂ and optional VOC monitoring in a single personal detector for multiple applications.
- Infrared flammable and CO₂ sensing: IR technology works in low or oxygen-free atmospheres and resists common sensor poisons for reliable %LEL measurement.
- Confined space ready: Pumped or diffusion versions, automatic flow plate recognition and guided Pre-Entry Check mode streamline entry testing and remote sampling.
- Engineered for hazardous areas: Rugged housing, high ingress protection, strong multi-sensory alarms and hazardous area approvals support demanding industrial and offshore use.

Overview of Crowcon Gas-Pro IR
Comprehensive multi-gas protection in demanding environments
Crowcon Gas-Pro IR is designed for industrial and offshore operations where personnel face combined toxic, flammable and oxygen-related hazards. Up to five sensors can be configured in one personal detector, enabling simultaneous monitoring of flammable gases, oxygen, CO₂ and a wide range of toxic gases, with variants available that add a PID sensor for VOCs. This breadth of coverage supports typical risks in upstream and downstream oil and gas, fuel storage, aviation fuel handling, chemical and pharmaceutical production, plastics manufacturing and routine confined space entry.
Customisable sensor combinations, including dual toxic options, allow each detector to be specified around site-specific hazards. Confined Space Entry variants are pre-configured for typical CSE risks, helping standardise devices across teams and simplifying selection for supervisors and permit issuers.
Infrared sensing for flammable gases and CO₂
The IR sensor at the core of Crowcon Gas-Pro IR measures flammable gases and CO₂ using dual-wavelength beams, one absorbing and one non-absorbing, to deliver accurate %LEL readings with built-in cross-checking. Unlike pellistor technology, the IR sensor operates effectively in low or oxygen-free environments, making it suitable for inerted tanks and oxygen-depleted spaces where conventional catalytic sensors cannot function.
The IR design is highly resistant to poisoning and contamination, including silicon-related effects that commonly impact pellistors. This resilience reduces unexpected sensor failures and minimises the frequency of sensor replacement, supporting lower maintenance effort and reduced ownership costs in harsh or contaminated atmospheres.
Integrated VOC monitoring with PID options
Where VOCs are a concern, Crowcon Gas-Pro IR can be configured with an integrated PID sensor using a 10.6 eV UV lamp. This enables detection of a broad range of VOCs such as solvents, paints, glues and fuel vapours, providing earlier and more sensitive indication than standard combustible gas channels alone. Five-gas variants can combine IR flammable sensing, oxygen, multiple toxic sensors and PID in one device, reducing the need for personnel to carry separate VOC instruments.
Pumped, diffusion and remote sampling flexibility
Crowcon Gas-Pro IR is available in diffusion and pumped versions to suit day-to-day personal monitoring and formal entry procedures. Diffusion detectors offer low-burden continuous protection, while pumped variants use an internal pump, activated via a flow plate, to draw samples prior to entry. Automatic fail-safe flow plate recognition confirms correct configuration in pumped mode and helps reduce the risk of user error.
Accessories such as water traps, hand aspirators and sampling tubes support remote sampling over significant distances, enabling checks of tanks, ducts, void spaces and structures on ships or offshore platforms. Marine approvals and Marine Equipment Directive options extend suitability to marine and offshore marine applications.
Simple operation and guided pre-entry checks
A single-button interface controls all key functions, supporting straightforward use while wearing gloves or other PPE. The top-mounted display ensures gas readings remain visible when the detector is clipped to clothing or a harness, improving situational awareness without needing to unclip the instrument.
The interface provides quick-view status, peak and TWA review and manual zeroing, allowing users to verify readings and exposure history quickly. A dedicated Pre-Entry Check mode guides personnel step-by-step through pre-entry tests, helping standardise confined space entry procedures and support compliance with site rules. TWA resume functionality allows time-weighted average calculations to continue across power cycles for more representative exposure tracking over extended periods.
High-visibility alarms and positive safety indication
Crowcon Gas-Pro IR combines a high-intensity audible alarm with all-angle dual red/blue LED indicators and a dual-colour backlight that switches between green and red for clear status indication. A built-in vibrating alarm provides an additional alert channel where noise levels or visibility are poor, ensuring that warnings are more difficult to miss.
Positive Safety indication gives a continuous visual confirmation that the detector is operating correctly. Programmable bump and calibration reminders assist in maintaining site procedures and help demonstrate that instruments are being checked and maintained in line with internal and regulatory expectations.
Rugged design for long shifts and harsh conditions
The detector’s robust housing and independently tested ingress protection to IP65 and IP67 help it withstand water and dust in challenging environments. A wide operating temperature and humidity range supports deployment in varied climates, from cold outdoor facilities to hot, humid process areas. Compact, lightweight and ergonomically shaped, Crowcon Gas-Pro IR is suitable for all-day wear using chest harnesses, straps, drop lines or other carrying accessories.
A rechargeable lithium-ion battery provides over 14 hours of typical operation, with only a modest reduction in pumped mode, supporting full shifts and overtime. Flexible charging options, including multi-region power supplies, desktop or wall cradles, USB leads and vehicle chargers, make the detector straightforward to deploy across fixed plants, mobile service teams and offshore installations.
Data capture, connectivity and fleet efficiency
Extensive data logging (including long-duration trend logs) and detailed event logging of alarms, calibrations, bump tests, on/off events and TWA values provide a strong record for investigation and compliance reporting. Direct PC connection and compatibility with automatic test systems enable efficient bump testing, calibration and configuration updates, reducing hands-on service time in larger fleets.
Where specified, compatibility with Crowcon Connect supports centralised fleet management, data analytics and compliance reporting across multiple sites. Multi-language and regional configurations with region-specific alarm levels assist global deployments while reflecting local practices. As part of a wider Crowcon portable gas detection portfolio, Gas-Pro IR enables standardisation of instruments, accessories and training across a site or organisation, helping reduce spares inventory and simplify support.
Support resources and long-term value
Crowcon Gas-Pro IR is supported by video tutorials and detailed manuals, covering activation, alarm behaviour, charging, flow plate use, PEC testing and bump testing. Technical support, training and demonstrations, often provided via distributors, help new users adopt the instrument quickly and reduce the likelihood of operational errors.
Over its service life, the durable construction, IR sensor resistance to poisoning, extensive logging and fleet tools combine to minimise downtime and unexpected costs, while maintaining robust, everyday protection for personnel working in hazardous industrial and offshore environments.
