Designed specifically for testing thin linings and coatings, in which low voltage output is required. It achieves this by using electronic circuitry for fine control of a DC-pulsed voltage. Also incorporates a thermal cutoff and transformer isolation for safety.
Key Features and Operating Characteristics:
It has a control knob on the high voltage handle to adjust the output voltage. Circuitry is fused, with with ON/OFF switch. The metal control unit has a carrying handle and non-skid rubber feet. The High Voltage Probe is made of durable plastic, with a 6 ft. cord. The High Voltage Probe is made of durable plastic, with a 6 ft. cord.
Output voltage is adjustable from 2,000 to 20,000. Output frequency is 500 kHz, DC pulsed. Output current is approximately 0. 1 mA maximum. Separate models operate from either 115 or 230 VAC, 50/60 Hz. Overall dimensions: 7x5.5x6.5 in. with 11x2.5 in handle. Weight: 13 lbs.
Key Applications and Accessories:
Can detect pinholes in thin linings:
- plastic, glass, or rubber linings, 1/16 to 1/4 in. thick, on metal tanks
- holidays” (voids) in thin coatings or paint on metal or concrete surfaces
- insulation on wires
Accessory electrodes included are the 12201 Spring Tip and a 12461 Electrode Shunt for use with other electrodes. Other accessories electrodes facilitate testing larger surfaces, include the 12141 Fan Tip; 4 in. 12121 and 8 in. 12131 brass brush; 4 in. 12401 and 8 in. 12421 T-Tips. For work with glass, the 12111 Spring Tip is useful.
The 12701 Peak Voltage Calibrator accessory permits accurate measurement of the output of this model.
