This Current Probe is designed for use in utility and industrial environments. The unique ergonomic design allows it to easily clamp onto cables or small bus bars. It is assembled to the highest safety and performance standards including the CE Mark and is UL approved for Canada and United States.
This Current Probe is designed for use in utility and industrial environments. The unique ergonomic design allows it to easily clamp onto cables or small bus bars. It is assembled to the highest safety and performance standards including the CE Mark and is UL approved for Canada and United States.
This AC Current probe is range selectable and offers 3 switch selectable ranges of 20, 200 or 2000AAC. Measurement range of 100mA to 1200A AC. Large jaw opening accommodates conductors up to two 500MCM conductors. This probe has a voltage output proportional at the current measured in the jaw of the probe. The SR661 has an integral 6.5 ft (1.98m) lead terminated by BNC connector. The high accuracy and wide frequency response makes this probe an excellent choice for use with oscilloscopes.
