TH-170 Portable Metall Hardness Tester

Three different models:

Impact D
Standard model

Impact DL
Special model for Hardness Measurement in extremely confined spaces

Impact C
Special model for Hardness Measurement on surface hardened components, coatings, thin walled components. It has app. 1/4 impact energy of Impact D and Impact DL.

The Impact is a handy portable hardness tester with an integrated impact device. It can be used in any position, even upside down. Readings can be printed out immediately on a mini-printer or stored for later processing.

How can you benefit from the Impact?
The small portable Impact hardness tester with integrated impact device is designed for an extremely wide range of applications. It is especially recommended for Hardness Measurement on the shop floor. The outstanding features of the Impact include speedy and exceptionally user-friendly operation and high measuring accuracy, with an extremely low tolerance of ± 1.5%.

The hardness tester functions by releasing a small impact device on to the metal testing surface by means of a spring mechanism. The gauge's dynamic measuring procedure works by calculating the difference between the impact velocity and the rebound velocity of impact device.

The Impact hardness tester can be used on a whole variety of metals. A statistics program calculates the mean hardness value from a number of single readings.

Hardness Measurement on metal substances such as:

Steel, cast steel, cold work tool steel, stainless steel, grey/nodular cast iron, aluminium, cast aluminium alloys, brass, bronze and wrought copper alloys

Typical applications of the Impact include:
- large, heavy components or fixed machine parts
- serial products during the production process
- material identification in storage
- measurement on locations with difficult access

Conditions required for measurement:
- Minimum measuring area 10 mm x 10 mm
- Minimum curvature radius r of the measuring area, 30 mm, without adapter.
- Minimum curvature radius with screw-on V-adapter, 11mm.
- Samples weighing less than 5 kg and samples less than 5 mm thick should be placed on a solid base to prevent vibration.
- Samples weighing less than 2 kg should be fixed to a solid base with coupling paste.
