GM100 Digital Ultrasonic Thickness Gauge Meter, Range 0.047 to 8.85in, for Measuring Metal and Nonmetal Aluminum, Zinc, Silver, Gold, Tin, Iron, Steel, Copper, PVC, Glass, Zirconium, Nylon

new

• Fast and Accurate Measurements: The ultrasonic thickness gauge measures from 0.047 to 8.85 in / 1.2 to 225mm, with a resolution of 0.01mm. The lower limit of pipe measure: Φ20x3mm/ 0.118inch (steel) You can get accurate readings (±1%H+0.1mm) in inches or millimeters in just 0.5 seconds.
• Adjustable Sound Velocity: Easily change the sound velocity from 1000 to 9999 m/s, It will automatically calibrates the zero point to correct system errors during measurement, to get the most accurate results.
• Multi-Functional: The LED backlit screen is easy to read in the dark, the button lifespan is over 10,000 times, the sound velocity measurement function lets you know the sound velocity of the material directly, avoiding the trouble of referring to the table or converting the sound velocity, and the coupling state prompt will prompt you whether the coupling state is normal, while providing you with storage for 10 thickness values ​​and 12 sound velocity values, in addition, low battery indication, manual and automatic power off help you save power.
• Widely Used for Measuring Metals & Non-Metals: For example steel, Aluminum, zinc, silver, gold, tin, iron, steel, copper, SUS, acrylic resin, glass, magnesium, nickel, titanium, zirconium, nylon, and any other ultrasonic wave conductor as long as it has parallel top and bottom surfaces.
