AEMC MN261 AC Current Probe, BNC, 100mV/A, 24A, 10mV/A, 240A

Regular price $ 272.00 CAD $ 268.21 CAD Sale

This small and compact Current Probe is designed to meet the most stringent demands in industry and electrical contracting. Model MN261 meets EN 61010, 600V, Cat. III safety standards and is CE Marked and UL approved in Canada and United States. Features a measurement range of 0.5 to 240A AC.

The MN261 is a high sensitivity probe with voltage outputs (100mV/A and 10mV/A) and combine two switch-selectable ranges of 20A and 200A, thus permitting accurate measurements at low and high levels. The MN261 is designed for oscilloscopes and other BNC terminated instruments. It has two performing ranges (20A, 200A) both voltage output (100mV/A and 10mV/A) and 40Hz to 10kHz response.
