The D. E. Stearns Company, the originator of the holiday detector, introduces the Model 10/20 high voltage holiday detector. The Model 10/20 is the product of more than three years of development and two years of testing in the field. The instrument represents the latest in electronics in the industry, with a new design and numerous improvements.

This pulsating DC holiday detector with regulated voltage has a range of 800 volts to 35,000 volts, giving complete coverage for coating specifications. The instrument has been ergonomically designed with an angled handle and an open grip design that takes into account different hand and glove sizes.


Of the new features, one of the most important is the safety switch. This trigger system provides greater jobsite safety for both the operator and nearby personnel and is very easy to use. Simply release the trigger, and the instrument instantly turns off. The handle must be held down on the grip to operate the instrument, and the unit is shut down immediately when the handle is released. This feature will increase jobsite safety as an instrument cannot be left energized while unattended.
