Product Description
Fluke 2491945 Insulation Tester is a robust handheld digital instrument engineered for effective insulation resistance testing across a voltage range of 50 V to 1000 V, combining multimeter functions ideal for industrial and commercial electrical maintenance and fault diagnosis.
It operates on AA batteries, delivering approximately 1000 hours of battery life, making it suitable for extensive field use. The tester features a digital display with 6000-count backlight, ensuring clear and precise readings even in low light.
Designed with safety as a priority, this model complies with CAT IV 600 V and CAT III 1000 V safety standards, protecting users in demanding electrical environments. It auto-discharges capacitive voltages up to 1 μF and inhibits insulation testing if terminal voltage exceeds 30 V to prevent live circuit testing.
Environmental resilience is assured with operation from -20°C to 55°C and non-condensing humidity levels up to 95% within specified temperatures. Its compact dimensions (Length: 203mm, Width: 100mm, Height: 50mm) and a weight of 624 g make it highly portable.
The tester is widely applicable for preventative maintenance on motors, drives, switchgear, panels, transformers, cables, and VFD-driven equipment diagnostics. Operates with a 1 mA nominal test current to limit stress on components.
Offers insulation testing resistance up to 2 GΩ for detecting high resistance. Includes essential accessories such as a remote probe, test leads, crocodile clips, a hard case, and K-type thermocouple. Meets CSA and CE approvals ensuring international safety and quality compliance.
