PaintChecker mobile LED Blue 591
Design and Function
The PaintChecker mobile LED blue 591 is a photothermal measuring device used for the noncontact and non destructive determination of coating thicknesses in accordance with DIN EN 15042-2.
Specially developed for the measurement of powder coatings before curing on various substrates such as steel, aluminium and ceramics. Cured coatings can also be measured.
The precise layer thickness measurement is geometry indepedent and therefore also possible on complex parts such as corners, edges or curved inner sides.
The photothermal measuring method used in PaintChecker mobile LED Blue is an indirect measuring method.
This 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 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 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.
