GAO Tek Inc.
GAOTek offers a large selection of crack detectors which are affordable, easy to operate and user-friendly. For some industries such as aviation, civil, infrastructure and space technology, even the slightest crack can lead to risks of hazards. There have been cases in the past where projects costing billions were destroyed in seconds due to a minute crack on the surface of the body. GAOTek provides trustworthy devices with various features that are helpful in detecting the smallest crack on an object.

STATOGRAPH® Product Family -
Foerster Instruments, Incorporated
The STATOGRAPH product family is used for testing surface cracks with the help of eddy current sensors. Eddy current testing for material cracks requires the appropriate evaluation electronics and probes adapted to the testing task. Depending on the test situation and test object, the STATOGRAPH family of test instruments offers the right system for this purpose.

Elcometer Limited
Elcometer 143 Crack Width Ruler is a simple gauge that has been designed to provide inspectors with a low cost alternative to a graduated microscope for determining the width of a crack in concrete or other building materials.
-
Elcometer Limited
The range also includes gauges used for the measurement of crack width in concrete and other structures.

Instron
Instron® Crack Opening Displacement transducers are designed specifically to perform standard ASTM and ISO fracture mechanics tests (both cyclic and static), covering all common specimen geometries (CT, SEB, Centre Crack, Arc Shaped). Each model offers class leading linearity, whilst being rugged enough to withstand the high energy release common in many of these applications and can be used at both elevated and sub-ambient temperatures. These gauges comply with requirements laid down in ASTM E399-09.

ROTO-PUSH -
Foerster Instruments, Incorporated
The ROTO-PUSH test station, which is integrated in production lines, serves to test cylindrical components for cracks in the liner surface. The testing configuration has to be rotated for automatic crack testing. After the test, the test pieces are sorted and separated. The continuous test run ensures a high testing rate, which increases profitability.
-
ROTO-SCAN -
Foerster Instruments, Incorporated
The fully automatic crack test system ROTO-SCAN was specially developed for the testing of rings. The mechanical equipment has been developed for the gentlest possible handling of the test pieces and features a compact and low-maintenance design. The test probes seamlessly scan the inner and outer contours of the test pieces, thus ensuring 100 % testing of the rings.

Micro Measurements
Structures can, and do, break, and this may be important and sometimes dramatic. It’s critical to determine whether a particular object made from a particular material can carry a particular load. If a true stress is ignored, the cost of not acting is usually far higher than the cost of dealing with the problem earlier. A good example is in ductile materials. The crack moves slowly and is accompanied by a large amount of plastic deformation around the crack tip. The crack will usually not extend unless an increased stress is applied. Geometrical irregularities, such as cracks, sharp corners and holes – which many times are ignored – may raise the local stress.

GLUON -
Shimadzu Corp.
The software uses notched specimens (CT specimens) to evaluate the material elasto-plastic fracture toughness value (JIC). The test is conducted at constant loading rate under test-force control or CTOD control and the load is removed to calculate the crack length. The software plots graphs of the crack length increase (Δa) and crack growth resistance (J value) from the acquired data, calculates the JIC value, and evaluates its validity.

Crackmeter -
PASI srl
The system consists of two plates that overlap for part of their length. One plate is calibrated in millimeters and the overlapping plate is transparent and marked with a hairline cursor. As the crack width opens or closes, one plate moves relative to the other. The relationship of the cursor to the scale represents the amount of movement occurring. These gauges are monitored over time, whilst being kept as far away from human disturbance as possible, to develop an understanding in the width and direction of movement of the crack.

V-Meter -
James Instruments Inc.
The V-Meter is an advanced ultrasonic, pulse-velocity test system widely used for quality control and evaluation of concrete structures. It can identify non-homogeneous conditions such as voids, cracks, honeycombs and frozen concrete.
