Through Coating/Paint Ultrasonic Thickness Gauge UM-1D New Tester Meter. UM-1D Ultrasonic Thickness Gauge has two operating modes: Standard mode and Coating mode. The operating principle of coating mode is E-E (echo-echo). When there is coating or oil paint on the surface of the object, the net thickness of the material can be directly measured neither without necessarily removal of the coating nor without the calibration.While the defect of this mode is that the measuring range is relatively narrow: 0.118''-0.709'' (with standard probe). The operating principle of standard mode is P-E.
With the covered coating, the measurement will not be very accurate, so the coating should be removed before measuring in standard mode. The advantage of this mode is that the measuring range is relatively wide: 0.031''-19.685'' (with standard probe). Standard mode: P-E (pulse-echo) method with dual-element probes. Coating mode: E-E (echo-echo) method with dual-element probes. Selectable: 1-point calibration: normal measurement.
2-point calibration: curve surface measurement or other special application with a high precision. 0.8mm to 300mm; 0.031in to 11.81in in standard mode. 3.0mm to 18.0mm; 0.118in to 0.709in in through coating mode. Depending on probe, material and surface condition. 128×64 dot-matrix LCD screen (1.65in×2.24in; 42mm×57mm).EL backlight and switchable contract ratio. Digit height: 0.54in or 13.75mm. 4 Hz in standard measurement mode.
25 Hz in MIN capture mode. 1000 to 9999 m/s; 0.039 to 0.394 inch/µs.Two 1.5V AA alkaline batteries. Warning with low battery voltage. Up to 200 hours (without backlight) with alkaline batteries, depending on operating mode. After 5 minutes of non-use.
5.86in×2.87in×1.25in; 149mm×73mm×32mm (H×W×D). Up to 1in: ±0.002in or ±0.1mm. H is the height of the testing object. ±0.001in or ±0.1mm. Sat, 18 Mar 2023 15:07:19 GMT 638147776398102521 0700738A5C161B1B.
