• 18-hour battery life – Safely work multiple or longer shifts between charges, covered by the 18-hour battery life
• Backlit display – Large, clear display with backlight and option to flip the screen 180 degree for easy viewing whilst worn
• Positive Safety indicator – A simple ‘traffic light’ status indicator which, at a glance, provides visual assurance of operational and compliant status to both users and supervisors (green light – working safely, red light – attention required)
• Intrinsically safe – ATEX approved and UL Class 1 Div 1 for operation in a wide range of hazardous environments
• Dedicated sensors – One sensor for every gas ensures effective, fast and reliable detection
• Multiple alarms – Audible 95dB alarm, bright red/blue LED’s and vibrating alerts provide effective warning to gas hazardous

Overview

T4 is Crowcon’s personal protection solution for detecting the four most common gas hazards:

• carbon monoxide
• hydrogen sulphide
• flammable gases 
• oxygen depletion

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.

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.

Now with improved detection of pentane, hexane and other long chain hydrocarbons.

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.

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.
