High Voltage Insulation Testers

High voltage insulation testers indicate breakdowns, grounds, and shorts. Use them to apply a high-voltage test at various steps in the manufacture or repair of electrical products. This permits early detection of insulation weakness or failure that might otherwise show up only in the actual use.
These testers are built with a breakdown light which also serves as an "on" light. This indicating light dims or goes out completely to indicate a problem.
In addition, 4 models have a built-in safety switch that immediately stops current flow in the event of a breakdown. Along with the visual indication of a problem these units also have a buzzer which signals a problem. These units will shut down in the event of a breakdown and will not start up again until the startreset button is reset.
All units are supplied with self retracting probed test leads. The probes are spring loaded and housed within the insulated fibre handles. The fibre slide buttons are pressed to expose the test probes. This safety feature minimizes the chance of accidental contact with the probes.
