The PEAKMETER MS5203 is a professional digital insulation resistance tester tailored for electrical maintenance and insulation diagnosis. It provides selectable test voltages (50V~1000V) and measures insulation resistance from 0.01MΩ to 10GΩ. Supporting automatic PI & DAR calculation, it enables comprehensive evaluation of cable, motor and transformer insulation status. Built with backlit LCD, data hold, MAX/MIN/AVG, it facilitates field measurement. Safety designs including live circuit alert, automatic discharge and overload protection are equipped. CE certified, this robust megohmmeter is an ideal tool for electricians and maintenance engineers.
