Portable Digital Thickness Meter UM-1 I.Introduction: UM-1 Ultrasonic Thickness Gauge measures the thickness of an object by precisely calculating the time of the probe sending ultrasonic pulse with the help of couplant to the object and passing through the object until the probe receiving the reflection form the boundary.The operating principle is P-E(pause-echo).The measuring range is 0.031~11.811inch. II.Parameter: Operating principle: Ultrasonic pulse/echo method with dual-element probes Probe zero adjustment Selectable: 1-point calibration: normal measuremen 2-point calibration: curve surface measurement or other special application with a high precisionV-path correciton: Automatic Measureing range: 0.8mm~300mm,0.031~11.8in Depending on probe, material and surface condition Resolution: 0.001in or 0.1mm Measuring error: Up to;1in: ±0.002in;or ±0.1mm Above 1in:+/-1%H H is the height of the testing object Repeatability: ±0.001in;or ±0.1mm Units: Selectable: inch or mm Display: 128*64 dot-matrix LCD screen(1.65*2.24in,42*57mm) EL backlight and switchable contract ratio Digit height:;0.54in;or;13.75mm;; Measurement update rate: 4 Hz in standard measurement mode 25 Hz in MIN capture mode Material velocity range: 1000-9999m/s,0.039~0.394inch/µs Power: Two 1.5V AA alkaline batteries Warning with low battery voltage Operating time: Up to 200 hours (without backlight) with alkaline batteries, depending on operating mode Auto shut-off: After 5 minutes of non-use Size: 5.86*2.87*1.25in,149*73*32mm(H*W*D) Weight: 200g,7oz ; Shipping and Packaging All items will be double checked and well packed before sending.Items will be dispatched within 2 business days after buyers pay for the order.
