The Wolf ATEX LED Headtorch range offers the perfect answer for applications where hands free lighting is essential, particularly where access is difficult, requiring climbing or crawling. They are ATEX approved for safe use in Zones 1 & 2 Hazardous Areas with the HT-650 certified for use in Zone 0 also.

The HT-400, HT-600 and HT-650 Headtorches have been Certified by Baseefa for use in explosive atmospheres. They are CE marked in compliance with the 94/9/EC (ATEX Equipment) Directive, for use in hazardous area activities within the EU. In addition they are IECEx Scheme certified for use in other countries throughout the world. The approval code allows the HT-400 and HT-600 to be used in Zones 1 & 2 hazardous areas with the HT-650 Certified for use in Zone 0 also. This approval code also covers all group II (industrial) gas apparatus groups, for potentially explosive gases, vapours and mists up to T4 temperature class, and group I M2 mining applications.

The HT-400 Headtorch is a mini, lightweight headtorch weighing only 90 grams including batteries, whilst the larger HT-600 and HT-650 models weigh 180 grams. They are all constructed from robust, highly durable, high impact thermoplastic materials which are chemical resistant and electrostatic non hazardous, and is fitted with a shatterproof polycarbonate lens. The headtorches have a tilt adjustment mechanism to allow the user to angle the light, and utilise bespoke optics for a broad spot beam suitable for close up hands free inspection and maintenance tasks.

The Wolf ATEX LED Headtorches have a long life, ‘fitted for life’, high power LED light source. The HT-400 has up to 75 lumens of light output, with an optimum light duration of approximately 8.5 hours a set of three AAA alkaline cells. The HT-600 and HT-650 has a more powerful light output of up to 130 lumens with an optimum light duration of approximately 17 hours from a set of three AA alkaline cells. The use of primary cells makes these product a more economical solution for personal lighting requirements in many applications arising in Hazardous Area confined spaces. The ATEX LED Headtorch range has been designed for single handed switching and is water and dust tight to a minimum of IP66.

The HT-400, HT-600 and HT-650 are supplied fitted with an adjustable removable fabric head band allowing the headtorch to be comfortably worn directly on the head for extended periods. A set of 4 helmet clips is supplied with the HT-400, HT-600 and HT-650 to allow the headtorch to be securely attached to a hardhat or safety helmet. The HT-650 is also supplied with an easy clean inert silicone rubber strap which allows the headtorch to grip to hard hats and safety helmets.
