LEEB U923 High Accuracy Coating thickness gauge is the instrument with the highest Measurement accuracy (Class A), the fastest speed and better Stability among domestic congeneric products. It can quickly, non-destructive and precise coating and platings thickness measurement, which can be used in both laboratories and engineering sites. By applying different Probes, it can meet a variety of measurement needs and is widely used in manufacturing, metal processing, chemical industry, commodity inspection and other testing fields.
1. Full Chinese interface operation, more convenient. 2. Using magnetic and eddy current thickness measurement methods, nondestructive measurement of magnetic metal substrate nonmagnetic coating layer and nonconductive coating layer thickness on nonmagnetic metal substrate. 3. 7 types of probes can be used (F400, F1, F1/90 °, F10, CN02, N1). 4. Measurement modes of single measurement and continuous measurement can be converted into male and imperial. 5. It has two working modes: direct mode and group mode. 6. There are five statistics: Average, MAX Maximum, MIN Minimum, Number of Tests, and Standard Deviation. 7. Provide a variety of Calibration methods: one test piece calibrated, two test pieces calibrated and five test pieces calibrated for system error correction. 8. With storage function, it can store 4 types of workpieces, each type of 26 groups, each group of 15 Measured values, a total of 1560 Measured values. 9. With deletion function, it can delete a single suspicious data or all data in the storage area. 10. The limit can be set, and the Measured value outside the limit can be automatically alarmed. 11. Built-in thermal printer, can directly print the current measurement data or select a set of data stored. 12. With the function of communication with PC, Measured value and statistical value can be transferred to PC for further processing. 13. There is a beep prompt during the operation. 14. There are two shutdown methods: manual shutdown and automatic shutdown.
This instrument uses magnetic and eddy current two thickness measurement methods. Magnetic method (F-type probe): When the probe is in contact with the coating layer, the probe and the magnetic metal substrate form a closed magnetic circuit. The existence of the nonmagnetic coating layer changes the magnetic circuit magnetoresistance. By measuring the change, the coating layer thickness can be deduced. eddy current method (N-type probe): Using high-frequency alternating current to generate an electromagnetic field in the coil, when the probe is in contact with the coating layer, eddy Current is generated on the metal substrate and has a feedback effect on the probe coil. The thickness of the coating layer can be derived by measuring the size of the feedback effect.

1. Select the appropriate Probe according to the measurement requirements and install it. 2. Turn it on and select the Chinese Operating interface. 3. According to the properties of the matrix material (magnetic or nonmagnetic) and the cover layer, choose the magnetic method or the eddy current method Measurement mode. 4. Calibrate the instrument by selecting the appropriate Calibration method (e.g. one or two specimens calibrated). 5. Measurement mode (single measurement or continuous measurement) and working mode (direct mode or group mode). 6. Vertically and smoothly contact the probe with the coating surface to be tested for measurement. 7. View and record measurement data, the instrument can display statistics (average, MAX Maximum, etc.). 8. For storage, the data can be stored in the specified artifact categories and groups. 9. The current data can be printed or stored through the Built-in Printer, or the data can be transferred to the PC through the communication function. 10. After the measurement is completed, choose manual or automatic shutdown.
• Measuring method and Probe should be correctly selected according to the type of substrate and cover layer before measurement. • Measurement accuracy must be calibrated before use. • For measurement, the probe should be in vertical and smooth contact with the measured surface. • The radius of curvature and area of the workpiece to be measured must meet the requirements of the instrument (e.g. minimum convex radius of curvature 1.5mm, minimum concave radius of curvature 9mm, minimum area diameter φ 7mm). The thickness of the substrate should be greater than the basic critical thickness (0.5mm). • Pay attention to the Ambient Temperature (0~ 40 ℃) and Humidity (20~ 90% RH) range of the instrument. When managing stored data, use the delete function with caution. • When using the limit alarm function, it is necessary to set the upper and lower limits reasonably. • The instrument has a built-in lithium battery, please pay attention to charging in time. • Do not use in flammable and explosive environments.
