SANWA MG5000 High Voltage Insulation Tester

SANWA MG5000 High Voltage Insulation Tester | Advanced Digital Insulation Resistance Meter

Precision High Voltage Insulation Testing for Industrial and Power Equipment in Sri Lanka

The SANWA MG5000 is a high-voltage digital insulation resistance tester engineered for accurate measurement of insulation resistance in power lines and high-voltage equipment up to 5000V DC. Certified to IEC 61010-1 CAT IV 600V standards, this robust meter is ideal for electricians, engineers, and maintenance professionals ensuring electrical safety and preventive maintenance across Sri Lanka’s industrial, utility, and construction sectors.

Featuring five selectable test voltages (250V, 500V, 1000V, 2500V, 5000V) and a maximum resistance measurement capacity of up to 1 teraohm (TΩ), the MG5000 delivers fast, reliable results with a 1200-count LCD and 36-segment bar graph for intuitive visualization. Its advanced functions include Dielectric Absorption Ratio (DAR), Polarization Index (PI), auto discharge, auto hold, and data hold for enhanced operational efficiency and accuracy. Built with an IP54 dust-proof and splash-proof case, it is well suited for demanding field environments.
