The HA100 is a compact clamp-on current probe for smaller loads where compact size is important. Its measurement range is from 0.1 to 100 amps AC and is very small which is ideal for locking inside a crowded electrical panel during monitoring.
A good choice for smaller currents, measuring between 0.1 and 100 amps AC. The HA100 achieves a special spot in this range of current measurements.
Measuring up to 100 amps, it greatly exceeds the measurement capacity of the HA5 when you need a compact probe becasue space is very limited.
Measuring down to 0.1 amp, it has a measurement advantage over the HA1000 for very small loads.
Its compact design allows it to work in many situations where the HA1000 cannot fit, such as in small electrical panels and boxes.
