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.
