Overview
DONGRU DR370 Coating thickness gauge is a split Probe thickness gauge using eddy Current thickness measurement principle. It is suitable for the measurement of nonconductive coating thickness on nonmagnetic metal substrates such as aluminum, copper, stainless steel, such as paints, powders, plastics, etc. The measurement range is 0~ 1250 microns. The instrument is equipped with a large LCD screen with backlight function, clear reading, easy operation, suitable for 0~ 50 ℃, 20%~ 90% RH environment.
Features
1. Intelligent operation: There is a beep prompt during the operation, automatic identification of iron-based and non-iron substrate materials, support metric-inch (μm/Mil) conversion, with low voltage indication and manual/automatic shutdown function.
2. Excellent design: Appearance simple and portable, using intelligent touch buttons and anti-skid design, tight structure.
3. Precision Probe: Imported good metal probe, stable performance, wear resistance and pressure resistance, long life.
4. Clear display: large LCD screen with backlight, large font size display, clear and accurate reading.
5. Efficient measurement: Fast test speed, Sensitivity, good stability, providing two modes of continuous test and single measurement, continuous test can reduce human error.
6. Data management: MAX Maximum, MIN Minimum, average and measurement times can be counted, large-capacity storage can store more than 800 measurement data, and can be connected to a computer to read and print.
7.Flexible calibrating: support zero-point calibrating and two-point calibrating in two ways, two-point calibrating is more accurate.
Principle
DR370 Coating thickness gauge adopts eddy Current thickness measurement principle, according to the eddy current thickness measurement method of national standard GB/T 4957-1985, it can nondestructive measurement of nonconductive film thickness on nonmagnetic metal substrates.
Applications
Film thickness measurement of nonconductive coatings on nonmagnetic metal substrates such as Aluminum Panel, such as paints, powders, plastics, rubber, enamels, enamels, Electrophoresis, anti-corrosion layers, etc.
Steps
1. According to the measurement requirements, choose zero-point calibrating or two-point calibrating for instrument calibrating.
2. Place the split Probe on the surface of the coating to be tested.
3. Select single measurement or continuous test mode for measurement, and there is a beep prompt during operation.
4. Read the measurement results through the large LCD screen.
5. After the measurement is completed, you can view the statistical information (MAX Maximum, MIN Minimum, Average, number of measurements) or read the stored data by connecting the computer.
Notice
* Please ensure that the instrument is used in an environment of 0~ 50 ° C and 20%~ 90% RH.
* When measuring, the thinnest film thickness of the substrate should not be less than 0.3mm.
* The minimum size of the measurement surface is 10mm x 8mm.
* When measuring on curved surfaces, pay attention to the minimum radius of curvature requirements (convex 5mm, concave 25mm).
* The instrument error range is +/- 3%, please pay attention to the accuracy requirements when using.
* Please use 3 AAA alkaline batteries and pay attention to the low voltage prompt.
* Instrument does not include calibrating certificate and accompanying software.
