Designed for quality assurance and calibration routines, this verifier checks whether detectors are delivering the correct voltage (0.5-35 kV). It requires no external power, includes ground wire, and delivers results within the combined tolerances of both devices—ensuring compliance and safety before conducting coating tests.
DeFelsko PosiTest HHD Verifier
The PosiTest HHD Verifier simplifies verification of holiday detectors: connect the ground, apply the probe to the detector electrode, and read the displayed voltage. Lightweight, rugged, accurate to ±5%, and suitable for field or lab, it aids in maintaining confidence in spark-testing equipment performance.
