SAFETY HiTESTER 3258
World’s First Non-Metallic Contact Voltage Tester Measures 600 V With Optimal Safety
Discontinued
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.
CAT IV 600 V
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
