INTRODUCTION

MEWOI4460A Insulation Resistance Tester, also known as megohm meter, insulation resistance tester, for insulation resistance testing. This instrument is a high performance digital type instrument, with LCD large screen with backlight display, data hold, automatic discharge, automatic shutdown and other functions. The instrument has the functions of test timing and voltage monitoring. When the loop voltage is higher than 36V, the instrument will forbid tested to protect the safety of the tested objects and personnel. Insulation resistance value, test time, output voltage display with the same screen, also have the functions of measuring AC voltage, DC voltage. This series instrument maximum output voltage 5000V, the biggest test resistance value 200GΩ, maximum short-circuit current 2mA.

MEWOI4460A  Insulation Resistance Tester complete appliance is beautiful, wide range, high precision, high resolution, easy to operate, convenient to carry, accurate and reliable, stable performance, strong anti-interference ability. And with the shockproof, dustproof, moisture-proof structure, which is the telecommunication, the electric power, the meteorology, the computer room, the oil field, the mechanical and electrical installation and the maintenance and uses the electric power as the industrial power or the energy industry enterprise department commonly used but essential instrument. It is suitable for measuring the resistance of various insulating materials and the insulation resistance of transformers, motors, cables and electrical equipment.
