Catalog No. 752 - AC Current Probe

Cat. 752 AC Current Probe
Cat. 752 AC Current Probe

The TESCO AC Current Probe (Catalog No. 752) is specifically designed for use in industrial and utility environments. The unique ergonomic design allows it to easily clamp onto cables or small bus bars. It is built to the highest safety and performance standards including the CE Mark and is UL approved for Canada and the United States.

Excellent transformation and low phase shift, plus a broad frequency response, permit accurate measurements of current for power and power quality measurements. The high quality magnetic cores and uniform windings provide sensitivity for very low level current measurements, as well as measurements up to 1200A AC. the AC Current Probe provides an accurate voltage of 1mV/A. This voltage output enables instruments without current ranges to measure, display and log currents through an AC voltage range or measure very low AC.

TESCO’s AC Current Probe can be sold as is, or as a calibrated item by our ISO 17025 Testing and Calibration Laboratory.
