Probe H (HV1) is purposed to control hardness of galvanic coatings (chrome, copper, nickel), thin-walled and small-sized items.

The design of hardness testers TQ-4C provides full interchangeability of probes!

Probe H (HV1) is purposed for hardness measurement of following:

• Stable readings independent from force and time of pressing.
• Easy measuring in hard-to-reach areas.
• Ultra-small control area (from 1 mm).
• Control in slots and blind holes from 5 mm (not provided by rival devices).
• Invisible print on mirror-surface.
• Low sensitivity to the curvative of surface, thickness and weight of product.
