AP/W Holiday Detector High Voltage, Tinker Rasor

Model: AP/W High Voltage Holiday Detector - Portable Belt Worn

The Model AP/W includes the integrated peak reading voltmeter, also used in the Model APS, to measure and display the output voltage being applied to the structure.

Other significant features include the unique T&R Safety Handle. 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.

The Model AP/W 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.

Of the new features, one of the most important is the safety switch. This trigger system provides greater job-site 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 job site 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 of the instrument. 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" LED's 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 kilo-volts (kV). So, 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.

*Electrode choice is made from the the Full Circle Spring Electrodes, 4" to 36" pipe diameters, or the Half Circle Spring Electrodes, 0.75" to 8" pipe diameters or Wire or Silicone-Rubber brush electrodes, 2" to 8" widths. You may choose one electrode per instrument, within the size ranges listed. Other sizes are available at a pro rated cost. Please call or e-mail for more information: +1 (909) 890-0700 or Info e-mail.

This is the older style AP/W and it has been discontinued but Tinker & Rasor continues to support these units for our customers. For new orders, please see the "New" AP/W for ordering.
