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
Tip 1mm

The pro version includes the above as well as:
Tip 0,5mm
Tip 0,75mm
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.

TQC Rotational Viscometer according to Brookfield Method, allows quick determination of viscosity in laboratory, research centres, and during production. The intuitive, easy functionality. light weight, and the fact they are battery operated provide great versatility. TQC Rotational Viscosimeter can even be used as a portable instrument.

Its main feature, compatibility to the Brookfield method, allows comparative measurements with results obtained in quality control laboratories using standard rotational viscometers. (when used with the same spindle type and the same rotational speed)

Two different models are available, one with a fixed speed of 60rpm, the other one with a fixed speed of 20rpm.

The TQC Cross Cut Adhesion Test KIT CC1000 is used to test the adhesion of dry coats of paint on their substrate by means of a series of cuts through the coating. Two series of parallel cuts cross angled to each other to obtain a pattern of 25 or 100 similar squares. The ruled area is evaluated by using a table chart after a short treatment with a stiff brush, or adhesive tape for hard substrates.

The round cutting knife of the TQC Cross Cut Adhesion Test KIT CC1000 has eight cutting edges that can be changed easily by rotating the knife. The self positioning knife bracket of the TQC Cross Cut Adhesion Test KIT CC1000) ensures equal pressure on the cutting knife.

Each TQC Cross Cut Adhesion Test KIT CC1000 contains a grip with cutter, a brush, an illuminated loupe and a roll of adhesive tape acc. EN ISO 2409.

The new PosiTest Adhesion Tester conforms to international standards including ASTM D4541/D7234, ISO 4624/16276-1, AS/NZS 1580.408.5 and others. Both models have a hydraulic pump. The pump of the automatic version is electronically controlled and applies smooth and continuous pull-off pressure. This greatly reduces user effort and the risk of influencing the pulling process.
Self-aligning aluminum dollies enable accurate measurements on smooth or uneven surfaces

The internal memory of the Manual version stores maximum pull-off pressure, rate of pull, test duration and dolly size for up to 200 pulls. The automatic version stores maximum pull-off pressure, rate of pull, test duration, dolly size, pass/fail, nature of fracture and user notes for 100,000 pulls in up to 1,000 batches in its internal memory and pull rate, pull limit and hold time are user-adjustable with the impact and scratch resistant color touch screen with keypad for operation with or without gloves.

Every PosiTest Adhesion Tester pressure system is calibrated and certified to ± 1% accuracy using a NIST traceable load cel. Evaluating measured values on PC is possible by using an adapter and PC-software.

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.

TQC Abrasion scrub/ washability Test to perform an abrasion and washability test on coated panels to define the resistance of paint, varnish or related products to scratching, wearing and colour loss due to wet or dry abrasion. Simulating everyday wear from cleaning actions or general use.

The new abrasion scrub/washability tester allows for the most flexible adaptation of the wide range of scrub, abrasion and washability tests that are in use. First the base apparatus has to be selected, which is available in four models. A 110VAC and 230VAC model without pumps for dry tests, and a 110VAC and 220VAC model with pumps for dry and wet tests. Each base unit is completely flexible and allows for easy exchange of the tools used for testing.

The TQC Automatic Washability Tester is driven by a micro-step controlled electro motor which allows precise and steady speed and sinus wave form control. Operation is intuitive by means of a jog-dial switch and a multi-lingual operating menu on a large illuminated display.

The whole system fits into a small sized waterproof rugged casing that is allowed as carry on travel luggage and benefits your overseas travel plans.

The hull roughness is measuredThe Sensor unit is equipped with three non-slip wheels and a carbide tipped stylus and is moved over the ship’s hull in a horizontal way collecting series of measurements. A set of LED’s indicate the status of the instrument so operation is possible without observing the control unit. during in-docking and out-docking. The Hull Roughness Gauge measures the AHR value (Average Hull Roughness) of sea going vessels. AHR is the ‘mean’ of all the vessel’s hull roughness readings and is the measure against which ship’s performance is correlated.

The TQC Hull roughness Gauge consists of a Control unit and a Sensor unit.
