HZ-4025C High frequecy spark tester
    Test Voltage:1.0~15.0KV. Cable Diameter: 0~25mm. Output Frequency: 2.5-3.5KHz normal. Fast recovery time after fault (0.1s) The Sine Wave Spark Tester is a fast and reliable instrument used in distinguish wire faults and detecting bare wires. Its high-speed fault detection feature gives you prompt information without worsening the condition of the wire after the test. The use of high frequency (3KHz) enables a traditional commercial power frequency bead chain electrode to be shortened to 120mm HS015E Model. The Sine Wave Spark Tester is quality-assured to meet your needs.
