MARKERLITE
The Wolf Markerlite is a self-contained, high visibility led indicator which is CE marked to the ATEX directive and IECEx certified for safe use in potentially explosive zone 1 (IIC/T4) gas and zone 21 (IIIB/200°c) dust atmospheres.
Description
In dark and reduced visibility environments, the Markerlite can be used in many hazardous area applications to clearly highlight the position of personnel or hazards, ranging from personal identification on protective headwear, clothing and site bicycles to escape route, exit and equipment marking.
Two coin primary cells power an ultra bright ‘fitted for life’ LED light, available in white, red or amber, with switchable flashing (up to 65 hours output) or static (up to 25 hours output) functions, to deliver an excellent wide angle beam of 180° light, visible from front and sides.
The Markerlite can be securely fixed and left in position for extended periods of time to continuously highlight dangers and obstacles to minimise the risk of injuries and accidents – easily mounts on a headband strap or fixes to a tube using a cable tie (supplied) and grip pad stops rotation. Equally its small size and weight, less than 37mm in diameter and 23 grams with batteries, make it ideal for carrying on your person.
Built for longevity and total reliability, the Markerlite has robust single handed switching for operation and function selection, drop and impact resistant polycarbonate enclosure and lens and is IP67 dust tight and protected against the effects of immersion up to 1m under water.
The Markerlite is supplied ready to use with integrated clip, re-usable cable tie, batteries and instructions.
