ATEX LED HT-400 Headtorch
Zones: 1, 2, 21 and 22
The ATEX LED HT-400 Headtorch is the ideal compact headtorch for hands free lighting, particularly where access is difficult, requiring climbing or crawling and is CE marked to the ATEX Directive and IECEx certified for safe use in Zones 1 and 2 potentially explosive gas and Zones 21 and 22 dust atmospheres. The approval code also covers all group II (industrial) gas apparatus groups, for potentially explosive gases up to T4 temperature class, and group I M2 mining applications.
The HT-400 is compact and lightweight weighing only 90 grams including batteries and constructed from robust, highly durable, high impact thermoplastic materials, which are chemical resistant and electrostatic non-hazardous, and fitted with a shatterproof polycarbonate lens. The tilt adjustment mechanism allows the user to angle the light and the bespoke optics deliver a broad spot beam suitable for close up hands free tasks, and is designed for single-handed switching and water/dust tight to a minimum of IP66.
With a ‘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 from a set of three AAA alkaline cells. The use of primary cells makes it economical for personal lighting.
The ATEX LED HT-400 Headtorch is supplied fitted with an adjustable removable fabric head band allowing it to be comfortably worn, at a low profile, directly on the head for extended periods and a set of 4 helmet clips to allow it to be securely attached to a hardhat.
