Safety HiTester

Overview

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.

Key Features

• Non-metallic contact for optimum safety

• Capture the voltage value of covered electric wires

• Also ideal for metallic busbars and terminals

• Optimized for 400 V AC circuits
