With ferrous substrate (FE) and non-ferrous substrate (NFE) measurements, the composite UT343A coating thickness gauge features the characteristics of high precision and reliable performance. Based on the principles of electromagnetic induction and eddy current, the product detects the thickness of the non-magnetic coating on the magnetic metal substrate and the non-conductive coating on the non-magnetic metal substrate. Features: The measurement method conforms to the magnetic method of GB/T 4956 for measuring the thickness of the non-magnetic covering layer on the magnetic metal substrate. The measurement method complies with the eddy current method for measuring the thickness of the non-conductive coating on the non-magnetic metal substrate of GB/T 4957. Portable and streamline form design with anti-skid treatment, compact structure and light weight to fit your palm. With high-quality sensor, it features the characteristics of high precision, wear resistance and high stability. The screen display content can be rotated up and down for easy reading. Automatically identify ferrous and non-ferrous substrates. Adopts two thickness measurement methods of magnetic and eddy current, capable of measuring the thickness of the non-magnetic coating on the magnetic metal substrate and the non-conductive coating on the non-magnetic metal substrate. Quickly measure the thickness of paint coating with wide measuring range: 0-1750μm / 0-68.9mil. Adopts single-point and multi-point calibration methods to ensure accurate measurements. Warning lights in three colors (red, green and yellow) indicate the current value attributes. Sound prompts when turning on, turning off and measuring. The mass storage chip can store 199 sets of data. Widely used in automobile manufacturing, metal processing, aerospace, scientific researches, quality inspections, etc. Specifications: Model: UT343A Material: ABS Color: Red Power Supply: 2 x AAA battery (NOT included) Minimum Convex Radius of Curvature: 5mm Minimum Concave Radius of Curvature: 50mm Minimum Measured Area Diameter: 20mm Minimum Volume Thickness: 0.5mm Display: EBTN color screen Auto Screen: automatically rotate screen content Unit Switching: μm / mil Alarm Indication: When the value exceeds the set value, the LED light will flash according in the corresponding color.
