Overview
DONGRU DR330 Coating thickness gauge is a magnetic/eddy current dual-use Coating thickness gauge designed and developed in strict accordance with the national standard GB/T 8393-1996. It is suitable for the measurement of nonmagnetic coating thickness on magnetic metal substrates and nonconductive coating thickness on nonmagnetic metal substrates. Measurement range is 0~ 1250 microns. The instrument has two Test methods, four statistical functions, and two calibration methods, which are powerful, small in size, simple to use, convenient to carry, Repeatability is better, and performance is good.

13. Fine and small integrated design, easy to carry
14, Simple operation, Test speed
Principle
The DONGRU DR330 Coating thickness gauge uses the magnetic thickness measurement method and the eddy current thickness measurement method according to the different metal substrates. The magnetic thickness measurement method can nondestructive measurement of the thickness of nonmagnetic coatings on magnetic metal substrates (such as steel, iron) (such as galvanized, chromium, enamel, rubber, paints, etc.); the eddy current thickness measurement method can nondestructive measurement of the thickness of nonconductive coatings on nonmagnetic metal substrates (such as aluminum, copper, stainless steel) (such as paints, powders, plastics, rubber, etc.).
Applications
Magnetic metal substrate nonmagnetic coating measurement, nonconductive coating measurement on nonmagnetic metal substrate
Steps
1. Test method: continuous test or single measurement
2, calibrate: use zero point calibrate or two point calibration method
3. Probe placed on the measurement surface
4. Read measurement data
5. Use statistics to view MAX Maximum, MIN Minimum, Average and number of measurements
6. Store or export data through a computer connection
Notice
Make sure the thickness of the substrate is not less than 0.4mm.
- The minimum size of the measurement surface is 10 * 10mm
- Operating temperature range is 0~ 50 ℃, relative humidity is 20~ 90% RH
- Pay attention to the low voltage indicator and replace the battery in time
- Avoid measurements on surfaces beyond the radius of curvature (convex 5mm, concave 25mm)
- calibrate before use to ensure measurement accuracy
