The LD.25.IS intrinsically safe laser enables accurate construction and alignment of tunnels where being driven by tunnel boring machines, drill and blast, pipe jack or conventional hand techniques. The laser is intrinsically safe and therefore do not require explosion proof containment when working in gaseous environments such as methane/air mixtures. The laser is waterproof, rugged and constructed from stainless steel and brass. The unit is based on diode technology and powered by two 'AA' cells.
When used with the MCE designed adjustable gimbal, the laser is easily installed on tunnel walls and adjusted to a target.
