Portable electric experimental multi -functional monitoring protection device that uses

The utility model relates to an electric experimental specialized tool specifically is portable electric experimental multi -functional monitoring protection device that uses. The problem of lack the professional instrument that carries out real -time supervision to environmental parameter and electric energy mass parameter in the present electric process of the test is solved. The device includes that it works jointly to cross undervoltage protection module, humiture monitoring module and electric energy quality monitoring module from the double entry, carries out the voltage protection to testing instrument to indicate on -the -spot humiture situation and electric energy mass parameter through bee calling organ and LCD display screen to the site work personnel. The utility model discloses the integrated level is high, the dependable performance, and small in size can not produce any influence to testing instrument's power electric energy quality in the use. When improve examining and repairing test efficien
