Vitrek has introduced a 140kVdc 100kVac smart bench-top test probe. Called HVL-150, it is intended to expand the measurement range of the firm’s Model 4700 precision high-voltage meter. The probe has a proprietary low thermal coefficient attenuator that minimises the effects of self-heating (0.2ppm of reading per KV2), and low capacitance for ac measurement. Alone, ...
