Ideally designed for non-invasive checks of insulation condition, the DT-339 allows you to perform tests without powering down the installation or disconnecting equipment - saving you time, without compromising on quality or safety.
The unique jaw design of the DT-339 eliminates the influence of adjacent current conductors, and minimizes the effects of external magnetic fields, even at low currents. This allows you to perform accurate and reliable tests in today’s crowded electrical environments. The tough and high quality clamp design of the DT-339 guarantees high stability for long-term repeatability.
