WB2681 Insulation Resistance Tester

The WB2681 Insulation Resistance Tester is a precision measurement instrument engineered for comprehensive insulation performance evaluation of electrical equipment. By applying regulated high-voltage DC test potentials, this instrument delivers accurate insulation resistance measurements of the Device Under Test (DUT), enabling rapid identification of insulation degradation conditions including aging, moisture ingress, and physical damage. These measurements provide critical data for ensuring electrical safety throughout equipment lifecycle phases.

The WB2681 incorporates industrial-grade high-precision resistance measurement circuitry and low-ripple voltage generation technology to ensure measurement reliability across diverse testing requirements. The instrument features both timed testing and manual testing operational modes, complemented by audible and visual alarm systems that activate when measured resistance values fall below user-defined threshold limits. This configuration establishes the WB2681 as an essential insulation testing solution for research and development validation, production quality control, and field maintenance applications.
