The Model 10/20 Holiday Detector

Model 10/20

Model 10/20

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.

For more information, see the Model 10/20 Product Release.

The Model 14/20 Holiday Detector

The 14/20 provides a voltage range from 800 volts to 35,000 volts, in 100 volt increments.
This range enables you to inspect any pipe coating, from the thinnest fusion bonded epoxies to the thickest hot applied enamels. The Model 14/20 is also watertight and completely sealed against the elements, so it can operate in any locality. The 14/20 main instrument is worn on a belt, keeping most of the weight on the operator and not contributing to arm fatigue when used on tanks, floors, walls, or other non-pipe structures. Weighing only 8 pounds the Model 14/20 is the most lightweight detector on the market and is ideal for all kinds of rugged field use and inclement weather.
The "Safety Switch Feature".
The Safety Handle allows the user much more control over the instrument and does not allow the instrument to be left energized when unattended. This feature provides safety not only for the operator but also for all others sharing a job site.

M/1 Low Voltage Holiday Detector

The Model M/1

The M-1 is known Worldwide as the best choice for the inspection of thin film coatings (0 to 20 mils). The M-1 uses six "AA" batteries and advance circuitry to produce 67.5 volts. With onboard calibration verification, the M-1 can be checked in the field with no other test apparatus needed. An LED lights on the front panel when the unit is in calibration and when a holiday is detected. The M-1 comes complete ready go to work right out of the box. Headphones may now be used in noisy environments that drown out the normal audio signal. For more information see, The M-1 Instruction page.

Model 10, 20 and 20-S Holiday Detectors

--No longer in production--

STEARNS HOLDIDAY DETECTORS ARE DESIGNED FOR ALL TYPES OF COATINGS!
The Stearns holiday detector is a quality control inspection tool used to electrically locate defects in insulating coatings applied to metallic or concrete structures. These versatile units can be used to inspect coatings on pipelines, tanks, pilings or any similar surface.

STEARNS DETECTORS PROVIDE ACTUAL VOLTAGE FOR WHICH THEY ARE SET!
The solid state capacitor discharge system and the D C system are practically independent of battery voltage, permitting the unit to provide the actual voltage indicated on the 10 position switch.
The Stearns Model 20 and Model 20-S detectors convert low voltage direct current (rechargeable batteries) into high voltage pulses. Model 10 provides D C voltage. Either voltage, when applied to the protective coating, will locate defects by the formation of a visible spark and an audible beeping sound.

PRECISELY REGULATED FOR DRY OR DAMP COATINGS
Stearns detectors are virtually unaffected by damp coatings. The voltage does not change from early morning to end of day. Also provides the same voltage automatically on 2" to 48" pipe without resetting (+/-5%).
