These models are compact lightweight simple operation easy-to-use insulation resistance meters having a rigid structure and a new design of modern feeling.
Adoption of inner magnetic field type meter, which excludes influence of external magnetic field for an indicator needle portion, causes a stable indication to be obtained. The Auto discharge function has been installed. These models are in compliance with JIS C1302 1994 and IEC1010-1 CATIII 600V.



1. Equipped with the discharge function
2. Equipped with the MW measuring switch that enables both one-shot and continuous measurement with switch lock function.
3. DC voltage up to 60VDC can be measured.
4. AC voltage up to 600VAC can be measured.
5. Equipped with a strap to suspend from the neck to allow both hands to be used for easurement.
