Product Description

Product Description:
HZSQ-427 Digital dual clamp phase voltammetry meter is a high precision , low cost, handheld, two channel input measuring instrument specially designed for voltage ,current and phase measurement. Shell of this meter uses engineering insulation material, equipped with rubber protection sleeve, safe and reliable.

Features: 
1.Can withstand the voltage of 1000V / 60Hz between voltage input terminal and the shell, between iron core of clamp current transformer(current clamp) and clamp handle, between the secondary side winding coils. Between the two voltage input terminals can withstand the 500V/60Hz of the sine wave AC voltage, which lasted 1min.
2.Between insulation resistance, digital dual clamp phase volt ampere meter line and shell, between the two voltage input terminal: ≥10 MΩ.
