HT-I22 Model Test Finger Probe for Household Appliance and Electrical Safety Testing with IEC/UL Standards

When it comes to electrical safety, even the smallest detail matters. The shape of a probe, the curve of a fingertip, the applied force—each plays a role in determining whether a product truly protects users from accidental contact.

The HT-I22 Electric Shock Protection Test Finger Nail Probe is crafted to simulate a human finger nail under specific test conditions. It is commonly used in conjunction with standardized test fingers to verify accessibility to live or hazardous parts within household appliances, consumer electronics, power tools, IT equipment, and lighting devices.
