HA5 – 5 Amp High Accuracy Current Probe

Our HA5 Current Probe covers the measurement range from 20 milliamps to 5 amps, making it the best choice for measuring very small loads and the outputs of CT (Current Transformer) step-down circuits.


The HA5 Current Probe is the best choice for measuring very small loads and the outputs of Current Transformer (CT) step-down circuits.


Designed to monitor permanently mounted CTs (Current Transformers), the range of 20 milliamps to 5 amps gives the best resolution and accuracy for measurement circuits and step-down transformers.

The range from 20 milliamps to 5 amps is a great choice for accurate high-resolution monitoring of small 3 phase loads.  [NOTE:  For high accuracy non-intrusive testing of single phase loads, use the 120ADP accessory, for high accuracy of very small loads (down to 2 milliamps) use the HA-GFD].

The compact size of the HA5 allows it to be used in very confined spaces.

The light weight and special measurement range of the HA5 makes it a great choice for a second set of current measurement probes for your analyzer.
