The Crowcon Tetra 4 Gas Detector integrates advanced safety features and an intuitive, rugged design to provide ultimate protection for those working in harsh environments. When lives are at risk, the most reliable protection is a must. The T4 is known for its reliability and technical innovation, so you will be confident with your gas safety.

 

The Crowcon T4 alerts against the four most prevalent gas hazards including oxygen depletion, carbon monoxide, hydrogen sulphide and flammable gases. The built-in positive safety indicator has a 'traffic light' indicator to tell the user whether the monitor is safe to use or not, and it also includes a unique feature called TWA (Time Weighted Average) which ensures the gas exposure is calculated accurately over an entire shift - even if the gas monitor is switched off for a break or moved to another site. The Crowcon T4 ensures peace of mind with safety at all times.

 

With an 18 hour battery life, personnel can safely work for longer shifts – so expect an increase in productivity on site. The T4 is incredibly dependable owing to its thick, anti-shock rubber casing and the simple ‘traffic light’ status indicator that provides visual assurance of operational and compliance status. The clear display, single button operation and intuitive menu system helps minimise training and allows for easy operation - even whilst wearing gloves.

 

TWA Resume

TWA Resume ensures time weighted average (TWA) toxic gas exposure is calculated accurately over an entire work shift. The red line on the graph shows workers with other detectors risking overexposure to hydrogen sulphide (H2S) by switching their detector off for a lunch break. Only T4 provides the option to include previous measurements in the calculation when you switch your detector back on again and so prevent you exceeding your exposure limit. Because of TWA Resume (green line), T4 alarms at 14:00 when their 8 hour TWA reaches 5pm.
