According to the actual application requirements, Biuged offers three different types of thickness gauges which combine the Hall effect and Eddy current principles to measure the thickness of non-ferromagnetic coatings on ferromagnetic metal substrates(iron, cobalt, nickel and gadolinium) and the thickness of non-conductive coatings on non-magnetic metal substrates(copper, aluminum, magnesium, zinc, chromium, etc). The instrument is widely used in metal processing, coating, hardware, shipbuilding, aerospace and other fields.
◆ Iron and aluminum dual use. Identify substrate automatically, and fast automatic conversion. (BGD 545 & BGD 546)
◆ Sensitive response, and the data can be measured in 0.5 seconds.
◆ With simple design and small size, it is easy to carry and operate.
◆ Ruby probe has abrasion and corrosion resistance, which ensures long service life and can avoid errors caused by wear.
◆ Two units of μm/mil can be selected.
◆ The advanced digital probe is used to keep the zero position stable for a long time without drifting. The test data is stable after testing
the same position for multiple times.
◆ The thickness gauge adopts unique algorithm to solve the linearity of the instrument and ensure measurement accuracy. It doesn’t
need to be calibrated, only need zero adjustment.
◆ The good repeatability to ensure that it passes the inspection of Chinese national metrological testing.
◆ Available in three different modes: Fe mode, NFe mode and Fe/NFe mode (BGD 545 & BGD 546)
◆ Conform to standards：ISO 2178, ISO 2360, DIN/EN/ISO 2808, ASTM D1186, ASTM D1400, ASTM D7091, DIN 50981, DIN 50984
etc.
◆ BGD 547 is specially designed for measuring the thickness of ultra-thin coatings or platings below 10μm, and it adopts ultra-thin probe
design, which is especially suitable for measuring coatings on small workpieces such as screws and bolts. The probe adopts digital
oscillation technology and high-speed ADC acquisition, which ensure that the instrument has ultra-high measurement accuracy and
repeatability. In addition, BGD 547 also has the function of data statistics, which can store up to 9 measurement values and automatically
calculate the maximum, minimum, average and standard deviation of the measured data.
