Elcometer's 550 non-contact uncured powder gauge, the Mark IV, uses airborne ultrasonic technology to measure the cured thickness of uncured powder coatings over most any substrate.
Applications include smooth or flat metallic surfaces using steel or aluminum sub-base, curved surfaces as well as flat, rigid materials such as MDF, the company says.
This new design incorporates a new color graphic LCD display, which highlights all aspects of measurement process--signal strength, distance from the object, energy level, bound limits, number of samples and final thickness. Internal parameters allow for manual adjustment of calibration data and compensation for material shrinkage due to the curing process.
The Elcometer 550 has selectable measurement units (metric/USCS), a resolution of 1 micron, and measured material thickness can vary between 30 and 110 microns. Calibrated accuracy is plus or minus 5 microns or 5% of the coating thickness, whichever is greater.
According to Elcometer, the unit is capable of storing 200 measurements in non-volatile memory, and enhanced electronics allow for improved accuracy and faster calculations of the sample data.
