The 3213A46 Analog Insulation Resistance Tester is a professional-grade measuring instrument designed for evaluating the insulation integrity of electrical systems. Featuring a classic analog dial interface enhanced by modern manufacturing techniques, this device delivers instant visual feedback on insulation resistance values, making it ideal for routine maintenance and safety inspections in power distribution networks, industrial machinery, and household appliances.
The tester boasts multi-range measurement capabilities covering both low-voltage circuits and medium/high-voltage equipment. Its precision-engineered meter head accurately displays resistance values from 0.1MΩ to 2500MΩ, enabling technicians to identify gradual insulation degradation. The integrated vibration-damping system minimizes measurement errors caused by environmental disturbances, while the manually operated DC generator produces stable 250V/500V/1000V test voltages without requiring external power sources – a critical feature for field operations.
Constructed with impact-resistant ABS housing and ergonomic non-slip grips, the device ensures durability and comfortable handling during prolonged use. The oversized dial with luminous markings guarantees legible readings even in low-light conditions. Dual-scale display simultaneously indicates both insulation resistance and leakage current values, providing comprehensive electrical safety assessment. Equipped with alligator clips and probe connectors, it adapts to various terminal types for versatile application scenarios.
Key operational advantages include simplified single-knob control for range selection, reduced maintenance through dust-proof construction and modular component design, plus reliable performance in challenging environments (-20℃ to +50℃ temperature range with up to 85% humidity). The included custom storage case organizes test leads and accessories for convenient portability. This instrument serves as a cost-effective solution for electrical maintenance teams seeking accurate, durable, and user-friendly insulation testing equipment.
