Description

T4 presents innovative safety features as well as a robust and intuitive design, providing advanced protection to those operating in hostile environments. This portable multigas detector, extremely easy to use and repair, protects against the four most common gas hazards: carbon monoxide (CO), hydrogen sulphide (H2S), flammable gases and oxygen depletion (O2).

T4 contains a wide range of powerful features to make everyday use easier and safer.

TWA Resume

Unique to T4, the TWA Resume function ensures toxic gas exposure is calculated accurately over an entire shift, even if T4 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.

18 hour battery

With a battery life of 18 hours, T4 allows multiple or longer shifts to be worked between recharging.

Backlit display

Large transparent display with backlight and the ability to rotate the screen 180 ° to facilitate reading while wearing the device.

Positive Safety

Crowcon's visual 'traffic light' indication, provides constant visual assurance that T4 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.

Safety

Approved for Zone 1 ATEX and Class 1 UL Div 1 for operation in various environments.

Dedicated sensors

A sensor for each gas provides effective, fast and reliable detection.

Robust design

Crowcon's toughest portable yet, 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 in the dirtiest environments. Drop tested to 4m and well protected from water ingress through IP65 and IP67 certification, T4 allows uninterrupted working in the most demanding environments.

Multiple alarms

95 dB acoustic alarm, bright red / blue LEDs and vibration alarms provide an effective warning against the risks created by gases.

Ease of use

Offering you compliance, robustness and low cost of ownership in a simple to use solution. The large single button and intuitive menu system allows T4 to be operated wearing gloves with minimal training.
