Did you know

The Kyoritsu KEW 3125A is a high-performance 5kV digital insulation resistance tester. It has since been replaced by the KEW 3125B.
The KEW 3125A sits in Kyoritsu's range as a professional-grade, general-purpose high-voltage insulation tester, offering a balance of capabilities for various applications. It is positioned below more specialized models like the KEW 3127, which offers higher resistance measurements up to 10 TΩ, and above simpler analog models such as the 3132A.
The KEW 3125A is chosen for its wide test voltage range from 250V to 5000V and its ability to measure insulation resistance up to 1 TΩ, making it suitable for high-voltage equipment. Its diagnostic functions, including Polarization Index (PI) and Dielectric Absorption Ratio (DAR), along with a filter function to reduce noise interference, ensure stable and reliable measurements in industrial environments.

Model	Max Test Voltage	Max Resistance Range	Diagnostic Functions	Short-Circuit Current
KEW 3125A	5000V	1 TΩ	PI, DAR	1.5mA
KEW 3025A	2500V	100 GΩ	PI, DAR	1.5mA
KEW 3127	5000V	10 TΩ	PI, DAR, DD, SV	N/A
