FAQs
What gases can the Crowcon T3 detect?

The Crowcon T3 is a portable multi-gas detector capable of monitoring up to four gases simultaneously. Common configurations include oxygen (O₂), hydrogen sulphide (H₂S), carbon monoxide (CO), and combustible gases (LEL), making it suitable for confined space entry and industrial safety applications.

How long does the Crowcon T3 battery last?

The Crowcon T3 uses a rechargeable lithium-ion battery. A full 12-hour charge provides at least 14 hours of continuous operation, while a 5-hour charge from flat provides at least 12 hours of use when fitted with a flammable gas sensor.

How loud is the alarm on the Crowcon T3?

The Crowcon T3 features a powerful 95dB audible alarm, allowing users to hear alerts in noisy working environments. It also includes an internal vibrating alarm for additional warning in high-noise areas.

Does the Crowcon T3 have data logging?

Yes. The Crowcon T3 includes extensive data logging capabilities, storing more than 12,000 gas readings across four channels. Data can be recorded over approximately 50 hours at one-minute intervals.

Is the Crowcon T3 suitable for confined space entry?

Yes. The Crowcon T3 is widely used for confined space monitoring due to its ability to monitor multiple gases simultaneously, robust alarm system, data logging capabilities, and ATEX certification for hazardous environments.
