DeFelsko HHDVERIFY | PosiTest HHD Verifier | 0.5–35 kV, Pulsed DC
The DeFelsko HHDVERIFY is a calibrated standalone voltmeter for pulsed DC holiday detectors, including the PosiTest HHD. It reads 0.5–35 kV and continuously monitors the voltage at its probe tip once grounded to the detector being checked. Lightweight and battery powered, it lets inspectors confirm test voltage where a specification requires an independent meter.
- Voltage range 0.5–35 kV for pulse type detectors
- Resolution 10 V steps to 1 kV, 100 V steps above
- Accuracy ±5%
- Two-step operation; no external power required
- Includes 1.8 m ground wire, 3 AAA batteries and NIST traceable certificate
