FD-1-6, FD-1-12 Fuel Vapor Detector

    * Hermetically sealed meter--chrome-plated panel.
    * Simple "safe-dangerous" indicator scale.
    * Explosion-proof detector unit with spare element.
    * Complete with heavy-duty neoprene-insulated cable.
    * Easy to build and install on your boat.

All boat owners are safety conscious--particularly when it comes to the 
very real dangers of explosion from combustible fumes accumularing in 
the engine compartment, or in other sections of the craft. The 
Heathkit Fuel Vaopr Detector has been designed to set your mind at ease 
concerning feul vapor problems by indicating the explosion potential in 
whatever part of the boat the detector unit is placed.
 
The indicator panel mounts on or near your instrument panel--so the 
presence of fumes can be seen on the meter, before the ignition is 
turned "on". A three-color "safe-dangeroous" scale immediately shows 
if it is safe to start the engine. A pilot light on the front panel 
shows when the detector is operating, and it can be left on continuously, 
or just used intermittently. Having this reliable indicator right at hand 
is more than a convenience; it is a necessity, for the safety of everyone 
abord, and as protection for your investment in the boat itself.
 
The detector is connected to the indicator by a heavy-duty neoprene-insulated 
cable, highly resistant to the effects of oil and gasoline. A panel control 
enables initial calibration of the detector when installed. The indicator 
features a hermetically-sealed meter and a chrome-plated brass panel. It 
is very simple to build and install, even by one not having previous 
experience.
 
The FD-1-6 (6 volts DC) and FD-1-12 (12 volts DC) operate from your boat batteries. 
The kit is complete in every detail, even to the inclusion of a spare detector unit. 
It constitues a small price to pay for the safety of yourself, your family, 
and your boat!
