Hioki leads the industry in non-metallic contact test and measurement technology that promotes safety on the worksite. The 3258 is a line voltage tester that employs a coupling capacitance cancellation method to measure voltage in AC circuits without requiring metal-to-metal contact. Voltage can be measured safely at practically any location, on either insulated or exposed metal conductors.
