hydrogen sulphide (H₂S)
flammable gases
oxygen (O₂) depletion

Gases and Ranges:

Gas	Range	Resolution
Oxygen (O₂)	0-30% vol.	0.1% vol.
Flammable	0-100% LEL	1% LEL
Hydrogen sulphide (H₂S)	0-100 ppm	1 ppm
Carbon monoxide (CO)	0-1000 ppm	1 ppm

The Crowcon T4, offering you compliance, robustness and low cost of ownership in a simple to use solution, with one sensor for every gas, ensures effective, fast and reliable detection. The large single button and intuitive menu system allows minimal training and easy operation while wearing gloves.

Crowcon T4, is durable by design and includes an integrated rubber boot as standard. An optional clip-on filter cover, which is easily removed and replaced, ensures sensors are protected.

Crowcon T4, allows uninterrupted work, to make everyday use, easier and safer, containing features:

TWA Resume

Unique to Crowcon T4 Gas Detector, the TWA Resume function ensures toxic gas exposure is calculated accurately over an entire shift, even if it is switched off for a break or during travel to another site.
When most portable detectors are turned off, the algorithm that assesses TWA exposure assumes that it’s the end of the shift. When turned on again, these detectors act as if it is a new work shift, ignoring all previous measurements. The TWA Resume function however, provides the option to include previous measurements from within the correct time frame.

Multiple alarms

An audible 95dB alarm with bright red/blue LED’s flashing and vibrating alerts to the provide effective warning to gas hazards.

18-hour battery

With a battery life of 18 hours this allows multiple or longer shifts to be worked between recharging.

Positive Safety

Crowcon's visual 'traffic light' indication, provides constant visual assurance that the gas detector is operating soundly and conforms to site bump test & calibration policy. The bright green and red Positive Safety LEDs are visible to all and offer a quick, simple and comprehensive indication of monitor status to both the user and others around them.

Backlit display

Large, clear display with backlight and option to flip the screen 180° for easy viewing whilst worn.
