TQC Machu Scratching Tool to perform a Machu test (corrosion test) with. Each tool is provided with a 1mm width cutter to cut the coating down to the metal, complying with ISO 17872.
Two models are available:
The TQC Machu Scratching Tool Basic is based on the CC2000 model. with a self positioning knife bracket to expose the substrate with a perpendicular cut through the coating.
The TQC Machu Scratching Tool Professional is based on the CC3000 model with adjustable cutting depth and two ball bearings to guide the cut. This guarantees reproducible results.
Mandatory test in Qualicoat and QIB accredited laboratories.
The TQC Pendulum Hardness Tester has a lot of unique features that ease defining hardness by the König and/or Persoz method as described in ISO 1522. Both methods work on the principle that the damping time of a pendulum oscillating on a sample indicates the hardness.
The instrument has an easy menu-driven interface with jog dial. The automated electronic counting mechanism is not affected by reflections from the surrounding area. The water-level is located on the test specimen, rather than on the instrument’s base. Once the instrument is leveled further calibration is not required. The gas-spring supported transparent draft cover allows easy access to all parts of the instrument.
TQC’s Pendulum Hardness Tester is a modular system. The instrument itself can be used for both the König and- Persoz method. Both pendulums should be ordered separately. After placing the correct pendulum, switching between the two measuring methods only takes a push of a button. The Pendulum is positioned fully automatically by means of a stepper motor. Also the release of the Pendulum is automated through electro-magnetic system. The end of a test is indicated by a visual and acoustic signal.
The TQC Pendulum Hardness Tester base device is available as a 110VAC / 50/60Hz and a 230VAC / 50Hz model.
The TQC Shore Hardness Gauge is a reliable instrument for measuring the impression hardness of soft materials such as coatings, plastics and rubber. Equipped with a drag indicator, which holds the highest measured result. Delivery includes a simple test block.
Complies with: DIN 53505, ISO 868 and ASTM D 2240
The TQC Shore Hardness Gauge Test Stand is suitable for Shore A, C, and D* type Durometer. The test stand construction includes operating handle, adjustable glass stage, (height) adjustable Durometer fixture. With this test stand hardness tests of rubber or plastics with a Durometer can be performed more accurately and reproducibly.
When this Test stand is used with TQC Shore D meter an extra weight of 4000gr is necessary.
Order separately: TQC SHore Hardness Gauge (Durometer)
The TQC Hardness Pen is a pocket instrument for testing the hardness and wear/scratch resistance of materials such as coatings, lacquers, plastics or related products. A tungsten carbide tip is drawn over the surface with a defined constant pressure. The pressure on the tip can be changed using the slide or by changing the spring. A visual mark on the surface after use of the TQC Hardness Pen indicates a fail of the surface hardness or wear/scratch resistance. Can be used on flat and curved surfaces.
There are 2 versions available, the Standard and Pro.
The Standard version is supplied with 3 springs and one tip:
0-3N, graduation 10 g
0-10N, graduation 50 g
0-30N, graduation 150 g
The pro version includes the above as well as:
Pen holder with guidance wheels, which provides very stable load on tip and makes it easier to apply force.
The laser-engraved scale is clearly visible on the grey background.
