Some customers have questions on the probes with thruster and without thruster, herein we just talk about the difference.

Generally, the probes are applied to simulate the human’s finger, hand, tools and etc. to access to hazardous parts or live parts. In the test requirements to prevent access to hazardous parts, the probes should be applied appropriately force, the force is recommended by relative standards. The probes built-in thruster make it more convenient to use when force must be applied, and the probe without thruster must work with a force gauge to apply the force.

Both the probes with thruster or without thruster can pass the calibration from third-party lab authorized by ISO17025, users can choose the right one as per their needs.Normally, probes without thruster will only calibrate the sizes according to standards it concerns, but with thruster, both size and force will be calibrated.
