Probe AL (HV5) for hardness tester TQ-4C
The 65 mm long tip allows to measure hardness in hard-to-reach areas:
– in small diameter holes up to 62 mm deep,
– between the teeth of the gears,
– in grooves, recesses, etc.
– in small diameter holes up to 62 mm deep,
– between the teeth of the gears,
– in grooves, recesses, etc.
Probe AL (HV5) is purposed for hardness measurement of following:
- Carbonaceous and structural steels;
- Items with surface-hardened layers such as cementation, nitride hardening, high frequency current hardening;
- Heat-proof, corrosion-proof, non-corrosive steels;
- Plated coating (chrome), overlaying;
- Items of complicated configuration.
Advantages
- 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.

The design of hardness testers TQ-4C provides full interchangeability of probes!
Probe AL (HV5) is designed to monitor hardness in hard-to-reach places: in small diameter holes, grooves, in-between gear teeth zones, etc.
Requirements to controlled item:
- Items heavier than 1 kg and thicker than 3 mm need no additional preparation;
- Items lighter than 1 kg should be fixed in a vice clamp or on a support plate by fixing paste;
- Items with a thickness of less than 3 mm should be fixed in a vice clamp or on a support plate by fi xing paste;
- Roughness of controlled surface providing best measurement accuracy is 1.6 RA.
ATTENTION! There is a built-in Lemo plug-in in the probe. Connection cable is sold separately.
