T4 integrates innovative safety features and an intuitive, rugged design to provide advanced protection for those working in harsh environments. This portable multigas detector, which is exceptionally easy to use and service, protects against the four most prevalent gas hazards: carbon monoxide (CO), hydrogen sulphide (H2 S), flammable gases and oxygen (O2 ) depletion.
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 (H2 S) 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 5ppm.
I-Test is Crowcon’s fully automated solution for testing and verifying that your T4 are in a compliant state to carry out your daily work. Bump testing standards are getting tighter in all regions and the need for controlled bump and calibration records is a must. I-Test and the accompanying I-Test manager software makes this as easy as can be. It takes less than 1 minute to complete a bump test!
