High Sensitivity CAT IV 600V Flexible Current Probes

The high sensitivity CAT IV 600V flexible current probes are a high performance current sensor specifically designed as an accessory for CHK Power Quality instruments used on energised circuits and in CAT IV environments.

The high sensitivity coils are purposely designed to facilitate dual measurement ranges with upper limits of 500A or 3000A and lend themselves to a wide range of applications, avoiding the need to swap probes.
