Introduction: The UM-2 series of thickness gauges offer extremely high measurement performance with high stability and accuracy. We introduced the through-coating technology in 2006, and the UM-2D has this special feature that allows direct measurement of substrate thickness without removing the surface coating of the test object. Coatings suitable for this function are: paint layers, plastic coatings, etc. This function is achieved by measuring two consecutive bottom surface echoes of the substrate. This mode also has more advantages: zero-free calibration, high stability, zero drift. Technical Parameters: Display: 128×64 dot matrix LCD with EL backlight for adjustable contrast Working principle: Pulse to echo mode (standard mode for common thickness measurement) Echo-echo mode (coating mode for net thickness measurement of substrates without removing the paint layer) Standard mode measurement range: 0.8mm to 300mm (depending on the probe and the material to be tested, the standard probe measurement range is 1.0-100mm) Coating mode measurement range: 3mm ~ 20mm (using the standard probe, only model UM-2D) Unit and display resolution: mm - 0.01, 0.1 inch - 0.001, 0.01 One point calibration: for regular thickness measurement Two-point calibration: Increases measurement accuracy when measuring curved wall thickness or for special applications V path correction: V sound path correction to compensate for the nonlinearity of the dual crystal probe Indication error: ±0.05mm (10mm or less) ±0.5% H+0.01 (10mm or more) Note: H is the thickness of the measured object Repeatability: ±0.05mm Measurement update rate: 4Hz Material sound velocity range: 1000～9999m/s or 0.0394～0.3937in/us Storage function: Divide 5 arrays to store 500 thickness values Minimum scan: Drag the probe along the surface of the object to be measured, and the instrument can automatically find the thinnest thickness of the measured value. Alarm function: The thickness limit can be set, and there is an alarm sound for the measured value outside the limit. Sound speed storage: can store sound speed of 5 different materials Working language: Chinese or English can be selected Communication interface: USB interface or RS232 serial port (optional) Application software: UmView software for measuring data transmission, storage, analysis and editing of documents (optional) Power: Two 1.5V AA batteries, when there is insufficient power, there is a low voltage prompt Operating time: Two 5th batteries, up to 200 hours Auto power off: 5 minutes after no operation, automatically shut down Working temperature: -10 ° C ~ +50 ° C, with special requirements up to -20 ° C Dimensions: 149mm × 73mm × 32mm (H × W × D) Weight: 200g (with battery)
