Theoptimisedscratchhardnesstester LINEARTESTER 249 Smartis intended, in addition to its original purpose of application, i. e. to establish the ability of a surfaces to resist damage by scratching, also for several other tests: Scribe/Scratch tests; To and frocycle abrasion tests; Crockmeter tests; MEK tests; tests determining the resistance against solvents in general or wipe test, respectively.
The LINEARTESTER 249 Smart is a tabletop device that is operated via a capacitive LCD display. The electromotive drive ensures a uniform forward motion of the slide. The test tool is lowered and lifted automatically when scratch/scribe tests are carried out. A multitude of different test tools are available (see table in the technical description below). The tools marked with (*) are made of Tungsten Carbide Steel, additionally covered with an extremely hard layer. Due to this layer’s “golden” appearance, any worn parts are visually very easy recognizable because the Tungsten Carbide Material under the “golden” layer has a distincly different color. With the optional available universal adapter set (see last page of the technical description) even also several user-specifc tool inserts can be used.
Principle of the Test: The test panel is fixed onto a mobile slide by means of clamping rails. Above this slide and held on two metal pillars is a reciprocating beam bedded in a free-moving manner and carrying the adequate test tool as well as a weight. The required scratching force in the range of (0.5 to 20)N is set by moving the weight along the reciprocating beam, making use of a setting scale (an additional load weight of (1 to 40)N is optionally available). The testing machine is equipped with a 4-position height adjustable load arm device with standard height of about 10 mm (+20/+40/+60 mm). To use the vertical adjustment, a set of sample clamping pieces are also required (Order No. 21010232). Operation (settings) is via a capacitive LCD display. To start a scratch/scribe test, the test tool is lowered onto the specimen when moving forward initiating the scratching process immediately. The test panel can be moved sideways so that a series of scratches can be carried out side by side with different force settings. Due to a ruler integrated in the slide plate, an uniform distance between the scratches can be achieved very easily. When testing insulating coatings on conducting substrates, an electric recognition of the through-scratching offers an additional security for setting the scratching force. For abrasion tests, crockmeter tests, MEK or wipe tests the test movement is carried out with the tool lowered onto the specimen, in preset cycles to and fro. For this, the guide plate has to be removed from the slide plate. The test speeds are freely adjustable. The LINEARTESTER Smart is equipped with variable stroke lengths.
The ERICHSEN SmartPen is used to determine the scratch resistance of surfaces; depending on the used module, it can be used to determine the resistance to scratching, the tendency towards metal marking and the durability of printed markings. With the ERICHSEN SmartPen, a modular hardness test pencil with digital test force setting and display (resolution 0.05 N) is now available. The SmartPen is supplied in a plastic case with three springs and a USB-C charging cable.

PaintChecker mobile LED Blue 591 gauge a photothermal measuring device used for the non contact and non destructive determination of coating thicknesses in accordance with DIN EN 15042-2. (metallic substrates), coating thickness ranges: 20-150 µm – powder, 50-250 µm – powder thk, 20-200 µm cured
Specially developed for the measurement of powder coatings before curing on various substrates such as steel, aluminum and ceramics.
Cured coatings can also be measured. The precise layer thickness measurement is geometry independent and therefore also possible on complex parts such as corners, edges or curved inner sides. The photothermal measuring method is an indirect measuring method which means that the measuring device does not measure coating thickness values directly, but that they are derived indirectly from the evaluation of the photothermal measurement signal. The Sensor
The sensor made of extruded high-strength plastic is designed for manual handling and contains, in addition to eye-safe positioning LEDs (UV light), the measurement data recording. The fabricated cable that connects the sensor and the controller unit is 0.8 m in length.
With the ergonomic, lightweight sensor, measurements can be made directly by hand. With its optomechanical structure, the sensor can also be used in the immediate vicinity of the application. The Controller-Unit
The controller-unit is contained in a rugged aluminum housing. All of the settings can be selected and modified conveniently with the membrane keypad using a context-related menu that is easy to understand. The USB connection is used for communicating with a PC. The software allows complete control over the measurement procedure and storage of measurement data. The measuring values are saved in measuring series for immediate or later use.
Accelerated weathering tester, UV aging test (UV radiation), moisture condensation. UV radiation is responsible for almost all the processes of photo degradation of durable materials exposed to the external environment. The fluorescent lamps used in the UV-BOX 636 simulate critical UV short waves and realistically reproduce the damage caused by sunlight. The types of damage that can be simulated with the UV-BOX are the following: color change, loss of gloss, chalking, cracking, cracks, blistering, veiling, brittleness, loss of strength and oxidation. Dew is mainly responsible for most of the moisture that occurs during outdoor exposure, much more than rain. The condensation system of the UV-BOX 636 realistically simulates dew and amplifies its effect through the use of high temperatures. The condensation process automatically purifies the network water used in the system. This is because the process of evaporation and condensation of water on samples is actually a distillation process, which allows to remove all impurities. UV-BOX can accommodate up to 48 standard samples (75 mm x 150 mm)¸it is possible to create special sample holders according to customer specifications. The operation is done via a modern touch screen panel. The UV lamps are not included in the delivery.
The accelerated UV aging test reproduces the damage caused by sunlight, rain and dew. In a few days or weeks of exposure of the samples inside the UV-BOX 636, damages occurring in months or years of outdoor exposure can be reproduced. Simulate aging due to external atmospheric agents, UV-BOX subjects the materials to alternating cycles of UV radiation and humidity at controlled high temperatures. The instrument simulates the effects of sunlight through the use of special UV fluorescent lamps and the simulation of the effect of dew and rain occurs through condensation or a spray of water (Spray option).

The Cathodic Delaminator is used for rapid checking of product quality and frequently quality control of coated metals. The apparatus consists of a control unit and a temperature control vessel (immersion container) with 8 test receptacles and circulator. Each test vessel has its own constant current source. So you can use up to 8 specimens for testing, independently of each other. The cathodic delamination allows the determination of infiltration of the coating in the damaged area and erroneous retreatments can be made visible (formation of bubbles during pinholes, scratches or stone impact).
Besides the usual applications such as salt spray test and cyclic corrosion tests (CCT), the specimens can be stored and tested in an atmosphere with controlled humidity. Constant settings, as well as rising and falling ramps for temperature and humidity can be programmed quickly and easily using a display with “Touch” function. The Model 618 is ideal for using fast ramps for temperatures or rel. humidity or for slowly increasing/ decreasing over several hours. An additional air conditioner allows the operator to carry out low-temperature cycles down to -40°C and dry heat up to +70°C.
