The PD687
Loop-powered Meter is mounted in an explosion-proof enclosure making it
ideal for location in hazardous areas. The 1 inch high liquid crystal
display can be read in a wide variety of ambient lighting conditions from
a distance of up to 50 feet. The PD687-EX has been FM, CSA and CENELEC
approved as explosion-proof as a complete product- not just the enclosure.
