Feature:1. Ultrasound Probe: Using ultrasonic dual element probe, with high sensitivity, can effectively reduce clutter, the probe shell is made of stainless steel, sturdy and durable.2. Timing Chip: Equipped with a professional timing chip, it can accurately calculate the propagation time of the ultrasonic pulse in the tested material.3. Automatic Operation: Automatically switch the gain and adjust the signal amplification, and can automatically select the appropriate gain according to the material type and thickness.4. 9 Sets Data Records: Can automatically record 9 sets of test data, and you can view the maximum value, minimum value and average value, which is efficient and reliable.5. 2 Measurement Modes: In the QC mode, the instrument can automatically judge the thickness of the material to be tested. In the statistics mode, the instrument automatically counts the latest 9 sets of data.6. Wide Application: Widely used for thickness measurement of ship hulls, piping, pressure vessels and structural steel to help determine if they need repair or replacement.Specification:Item Type: Ultrasonic Thickness GaugeMaterial: ABS, stainless steel, aluminumMeasuring Range: Approx. 0.8-350mm / 0.03-13.8inMeasured Value: 10-100mm: 0.01mm, 100-350mm: 0.1mmAccuracy: 0.8-10mm: 0.05mm, 10-350mm: 0.5% readingSound Speed Range: 1000-9999m/sProbe: 5MHz dual element probeDisplay: 240 x 160 dot array LCDUnit: Mm and inchPower Supply: 2 x 1.5V AAA alkaline battery (battery not included)Host Size: Approx. 142 x 72 x 28mm / 5.6 x 2.8 x 1.1inOperating Temperature Range: -10-60, 0-85%RH (non condensing)Storage Temperature Range: -10-60, 0-85%RH (non condensing).Package List:1 x Thickness Gauge1 x Couplant1 x Test Head1 x User ManualNote:Avoid irreversible damage caused by strong bumps and affect the measurement accuracy.
