SPY JM Voltmeter

En SPY JM Voltmeter delivers exceptional accuracy and versatility for verifying holiday detector voltage output in pipeline and coating inspection applications. Designed for everyday field use, this precision instrument features a clear digital LCD display that eliminates guesswork and interpretation errors, ensuring reliable readings every time.

Holiday detector output can be affected by weather conditions, moisture on the pipe, soil conditions, and improper grounding. The Model JM Jeepmeter is specifically engineered to accurately measure both pulse and DC voltage output, giving inspectors confidence that their equipment is operating at the correct voltage for coating inspection.

For pulse-type holiday detectors used on shrink sleeves, tapes, and coal tar coatings, the JM measures up to 35 kV pulse (rated up to 40 kV). For DC holiday detectors inspecting thin-film epoxy coatings, it measures up to 5 kV DC. Advanced electronics improve stability and repeatability, while automatic polarity sensing ensures accurate readings when used with pulse-type detectors.
