The Kyoritsu KEW 3123A is a professional-grade analog high-voltage insulation tester engineered for heavy-duty industrial applications. Specifically designed for testing high-voltage equipment like cables, transformers, and large motors, this dual-voltage megohmmeter provides reliable DC test voltages of 5000V and 10000V.

Built for the field, the Kyoritsu KEW 3123A features a rugged, drip-proof (IP41) design and comes in a durable hard-shell carrying case. Its dual-scale display automatically switches between ranges, utilizing color-coded LED indicators (Red and Green) to ensure clear, error-free readings even in low-light environments. With a measurement capability reaching up to 400GΩ, it is an essential tool for preventative maintenance and diagnostic testing.

Safety is paramount with the KEW 3123A, which includes an automatic discharge function to safely bleed off residual voltage from the circuit after testing is complete. The device also features a “Press to Test” lock-down button for extended insulation resistance monitoring. Whether you are performing routine safety checks or complex industrial diagnostics, the Kyoritsu KEW 3123A delivers the precision, durability, and safety required by electrical engineers worldwide.
