1.Description

BGD offers three different models of high-precision coating thickness gauges tailored to specific application scenarios. These gauges combine the Hall effect and eddy current principles for thickness measurement, enabling the measurement of non-ferromagnetic coatings on magnetic metal substrates (iron, cobalt, nickel, gadolinium) as well as non-conductive coatings on non-magnetic metal substrates (copper, aluminum, magnesium, zinc, chromium, etc.). They are widely used in industries such as metal processing, coatings, hardware components, shipbuilding, and aerospace.

Feature:
* Iron-aluminum dual-use, intelligent identification of the measurement substrate, and rapid automatic conversion (BGD 545 & BGD 546)
* Highly responsive, with measurements completed in 0.5 seconds
* Compact and portable design, ideal for on-site use
* Ruby probe tip with wear-resistant and corrosion-resistant properties, ensuring a long service life and minimizing measurement errors caused by wear
* Selectable units: μm/mil
* Advanced digital probe maintains stable zero position over extended periods, ensuring consistent measurement results at the same location
* Utilizes a unique algorithm to address linearity issues across the entire measurement range, requiring only zero adjustment without calibration to ensure measurement accuracy
* Excellent repeatability, ensuring compliance with national metrology standards
* Three measurement modes available: Iron-based measurement (Fe), Non-iron-based measurement (NFe), and Automatic identification (Fe/NFe) (BGD 545 & BGD 546)
* Complies with standards: GB/T 4956-2003 Measurement of Non-Magnetic Coating Thickness on Magnetic Substrates - Magnetic Method, GB/T 4957-2003 Measurement of Non-Conductive Coating Thickness on Non-Magnetic Metal Substrates - Eddy Current Method, DIN EN ISO 2808 Determination of the thickness of coatings and varnishes, JJG-818-2005 Calibration procedure for magnetic and eddy current coating thickness measurement instruments. (BGD 545 & BGD 546)
* BGD 547 is specifically designed for testing ultra-thin coatings (below 10 μm) and features an ultra-small probe-type measuring head, making it particularly suitable for measuring coatings on small components such as screws and bolts. The probe employs digital oscillation technology and high-speed ADC data acquisition, ensuring the instrument achieves ultra-high measurement accuracy and repeatability. Additionally, the BGD 547 features data statistics functionality, capable of storing up to 9 measurement values and automatically calculating the maximum, minimum, average, and variance of the measured data.
