Coating Thickness Gauge NOVOTEST TP-1M is a thickness gauge for measuring the thickness of various coatings on metals, and with connected specialized probes to the device, user can measure the temperature and humidity of air, surface temperature, calculate the dew point, and also measure the depth of grooves or surface roughness.
The device is very easy to use, ready to use right out of the box, and does not require special user skills. The minimum number of buttons and an intuitive menu makes it an ideal device of operational non-destructive measurement of the thickness of almost any coating with high accuracy.
Coating Thickness Knife Tester NOVOTEST TPN-1 (Paint Inspection Gauge) is designed to measure the thickness of both single and multiple layer coatings on any grounds, both metallic and non-metallic. The operation principle is based on the local cut (notch) of the coating at the tested place of object with following thickness measurement of this coating. The thickness of coating is determined by the width of notch, it is possible because of the special form of cutter of the instrument. The measurement is performed by any portable measuring microscope with a suitable measuring range and discreteness.
Coating Thickness Knife Tester NOVOTEST TPN-1 (Paint Inspection Gauge) complies with ISO 2808, ASTM B 4138, DIN EN 1071-2.
A precision measuring comb with a quadrangular and hexagonal shape, crafted from high-quality stainless steel that resists corrosion from acidic or alkaline substances.Wet film thickness gauges are designed to determine the thickness of coatings right after they have been applied to a surface.
The gauge features a series of notches along its edges, resembling the teeth of a comb. It can measure the wet film thickness of various coatings, such as paints, resins, lacquers, varnishes, gels, and more. Operation: 1) position the gauge at a 90° angle to the coated surface 2) ensure the gauge is in full contact with the surface 3) lift the gauge straight up 4) Examine the teeth of the gauge. The wet film thickness is between the highest tooth that has a coating on it and the next smallest tooth that remains dry.
Pencil-Type probe for coating thickness gauge is designed for precise measuring the thickness of electroplated (zinc, chrome) and dielectric (lacquer, paint, polymers, etc.) non-magnetic coatings on small steel parts. This probe provides high accuracy even on thin coatings, making it ideal for industrial applications, construction, and laboratory research.
Recommended use: this specialized probe is designed for measuring the thickness of zinc, chrome, and other electroplated coatings on fasteners and other parts with dimensions of just a few millimeters or less. If the objects being measured are not as small, we recommend using the F-0.5 probe, which is more convenient to use and has a slightly wider measurement range.
