Thickness Gauge for Field and Lab Research – Acoustic Testing Pro
Acoustic Testing Pro Thickness Gauge for Field and Lab Research is a high-precision device designed for both field testing and laboratory research.
Overview
Acoustic Testing Pro Thickness Gauge for Field and Lab Research is a high-precision device designed for both field testing and laboratory research. This product adopts two measurement principles: magnetic induction for ferrous substrates and eddy current for non-ferrous substrates. It enables rapid, accurate, and non-destructive measurement of coating thickness, ensuring reliable results across various applications. This device can be equipped with six optional probes, making it versatile for different testing needs. It features two working modes, DIRECT and BATCH, along with two measuring methods, CONTINUE and SINGLE, to meet diverse testing requirements. With a data storage capacity of up to 500 readings, it also provides statistical analysis including mean, maximum, minimum, standard deviation, and test counts. This product supports both zero and foil calibration for enhanced accuracy and conforms to international standards such as DIN, ISO, ASTM, and BS. It comes with useful functions like low battery indication, error alarm, backlit display, adjustable limits with alarms, and auto/manual shutdown. Equipped with a USB interface and an optional built-in printer, this device ensures easy data management and reporting. Overall, Acoustic Testing Pro Portable Digital Coating Thickness Gauge TM260 is a reliable, efficient, and professional-grade solution for precise coating thickness measurement in industries such as automotive, aerospace, construction, and research laboratories.
