T4 integrates innovative safety features and an intuitive, rugged design to provide advanced protection for those working in harsh environments.
- Carbon monoxide
- Hydrogen sulphide
- Flammable gases
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 (H2S), flammable gases and oxygen (O2) depletion.
TWA resume function – Unique to T4, this innovative feature 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.
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° for easy viewing whilst worn.
Rugged design – With a thick anti-shock rubber casing and drop tested to 4 metres on concrete, T4 provides dependable operation under the most demanding use.
Water & dust resistant to IP65 & IP67 – Provides protection in the harshest environments.
Dedicated sensors – One sensor for every gas ensures effective, fast and reliable detection.
Positive safety indicator – A simple ‘traffic light’ status indicator which, at a glance, provides visual assurance of operational and compliance 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 safe operation in a wide range of hazardous environments.
Multiple alarms – Audible 95dB alarm, bright red/blue LED’s and vibrating alerts provide effective warning to gas hazards.
Easy operation – Large single button and intuitive menu system minimise training and allow easy operation whilst wearing gloves.
