Are you facing the task of having to determine the hardness of large, non-transportable components? Do you still work with a Poldi Hammer? Do you need an economic and easy method for on-site hardness testing? In this case, we would recommend to you our small, compact, rebound hardness tester DynaPOCKET which has no trouble at all in solving such test tasks. This is possible because the instrument's size is yet smaller, it's yet faster in operation, and yet easier to use.
The GE Inspection Technologies DynaPOCKET Portable Hardness Tester integrates the impact device and display or evaluation unit into one instrument. This means: small dimensions, low weight, no cables. As a result, you'll have an extremely compact hardness tester at your disposal which really fits into any pocket, and goes with you everywhere without any problem. No matter which test location, which test position, and which test direction you wish to work in, the DynaPOCKET is the right instrument.
Needless to say, we have ensured easy and straightforward operation: All functions can be activated in the DynaPOCKET with just two keys. The DynaPOCKET makes hardness testing fast and easy as never before: switching on, measuring, and reading - in a matter of seconds! The hardness value is immediately digitally displayed on the large and easy-to-read LCD display.
The DynaPOCKET operates according to the rebound method in which an impact body is impelled against the test surface by spring force. Impact and rebound velocities are each measured in non-contact mode; the hardness value is calculated on the basis of these two readings. The harder the material, the higher the rebound velocity and the displayed hardness value. The rebound method offers measurement with high precision and reproducibility, and consequently an especially high test reliability.
Now, that's what we call easy testing: when using the DynaPOCKET, you'll measure immediately, everywhere, in any direction – and all this with constant accuracy. This is ensured by our patented signal processing which spares you the trouble of having to input additional correction factors for the impact direction, no matter if you're measuring in horizontal or overhead positions.
We even make the calibration of the DynaPOCKET easy for you: Standard conversion tables for nine material groups are stored in the instrument from which you can choose the one that suits your application. You'll easily recognize the material groups by the alphanumerical abbreviations displayed by the instrument (e.g. St for low-alloy / unalloyed steel and cast steel, GCI for gray cast iron, Cu for wrought copper alloys, etc.).
The measurement itself is child's play, and the measured hardness value is directly displayed. Of course you can decide for yourself whether you wish to see the single reading or the arithmetical mean or average value of a complete measurement set.
It goes without saying that the DynaPOCKET makes various hardness scales available for you to choose from. A conversion is possible to the following scales:
- HL Leeb
- HS Shore
- HB Brinell
- HRB Rockwell B
- HRC Rockwell C
- HV Vickers
- N/mm² Tensile strength
The DynaPOCKET is also able to make conversions according to the standard specifications DIN 50150 and ASTM E 140, provided the material group in question is low-alloy / unalloyed steel and cast steel. The instrument-specific conversion tables apply to the other materials.
The DynaPOCKET is an instrument for on-site hardness testing. Thanks to its compact size, it enables tests in almost any position, especially in places where the access is difficult due to the test object's geometry. Heavy, non-transportable components are also a case for the DynaPOCKET, the same as permanently installed system parts or machines.
Applications for the GE Inspection Technologies DynaPOCKET Portable Hardness Tester include:
Rebound hardness testing using the DynaPOCKET is mainly suitable for solid workpieces made of steel or cast materials. The following are typical applications:
- large, coarse-grain components with surfaces as rolled
- forgings with inhomogeneous surface structures
- workpieces made of cast materials of all types
- material sorting in material stores
- hardness testing of large series products during the production
The instrument and impact device are covered by a full one year warranty on parts and labor excluding replacement of the impact body due to normal wear and use.
