Stearns Model 14/20 Holiday Detector

Stearns combines its renowned solid technology with the innovation of regulated voltage to fashion quality instruments that are the top of the line in their field - the Model 14/20

The 14/20 provides voltage ranges, from 800 volts to 35,000 volts
This exclusive features 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.

Stearns Model 10/20 Holiday Detector

800 volts to 35,000 volts in one instrument

The Stearns 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.

10/20 Holiday Detector
With Safety Handle - Instrument will work only when handle is depressed



  • Output Voltage Range: Low 800v/High 3, 500v-35,000v
  • Accuracy: +/- 5%
  • 800 volts to 35,000 volts in one instrument
  • Safety feature for increased jobsite safety
  • LED Holiday Indicator - Easily seen in bright daylight
  • Digital voltmeter display
  • Volume controls for noisy environments
  • Regulated voltage
  • Large push button controls
  • Greater battery efficiency
  • Compatible with components and accessories of Models 10, 20 & 20S

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.

After setting the voltage, the instrument remembers the setting and the range so the instrument can be turned on and off as much as necessary without requiring further adjustments.

The instrument is controlled by an electronics package contained within the water impenetrable cover. All control switches are push button operations, with large operational areas, easy to manipulate while wearing gloves. Controls include On, Low and High voltage ranges, LCD voltmeter display, the voltage setting switch, Loud and Louder volume controls and the wand handle release button.

Just below the LCD voltmeter display is the visual alert for holiday indications. This alert is made of a cluster of “super bright” LEDs that are easily seen in bright daylight conditions.

The voltage selection switch is located just above the LCD voltmeter display and is sealed from weather and dust by a screw cap. Using the supplied screwdriver, the dust cap is removed and voltages are set by turning the voltage selector as shown in the graphics. On the Low voltage range, select between 800 volts and 8,000 volts. On the High voltage range, select between 3,500 volts and 35,000 volts.

The LCD voltmeter display shows voltages in kilovolts (kV). Thus, a voltage setting of 800 volts would be displayed as 0.8 and a voltage selection of 35,000 volts would be shown as 35.0. The audible alert speaker is located in the middle of the top of the instrument. The Loud setting is recommended for normal operations, where ambient noise levels are normal. For louder areas, where ear protection may be required, the Louder volume setting may be used.
