The TOYOKEIKI NH-349 is a robust and reliable analog panel meter designed for the critical task of measuring insulation resistance. Engineered for seamless integration into control panels and monitoring systems, it provides a clear, at-a-glance reading on a logarithmic scale that spans from 0 to infinity Megaohms (MΩ). Its durable construction, high accuracy tolerance of ±1.5%, and dedicated DC operation make it an ideal choice for continuous monitoring of electrical insulation integrity in industrial and commercial applications. The panel-mount design with secure screw terminals ensures a stable and lasting installation.
