In StockMake An Enquiry

The Crowcon Gas-Pro detects up to five gases, with diffusion or pumped model choices. A versatile gas detector with infrared sensors options for Flammable or Carbon Dioxide gases. VOC detection is possible with a PID sensor, ideal for chemical or refinery applications, mainly when used with tanks containing solvents.

Compact and rugged, suitable for harsh environments and easy to use, intuitive functionality and one-button operation minimise training time. For confined space work, the internal pump is automatically activated with the flow plate, for simple pre-entry checks. The pump capacity is 0.5l/m and will draw a sample of gas from 30 metres within 80 seconds. The top-mounted display with dual colour backlight (green/red) ensures easy visibility of readings and alerts.

+ve Safety provides continual visual assurance of unit compliance to the user and others.  Manage larger fleets of Gas-Pro detectors easily with Crowcon I-Test bump and calibration solution (additional option).
