A Basic Ultrasonic Thickness Gauge

GM-100 Product information:

Ultrasonic Thickness Gauges are designed to improve safety and ensure reliability of material subject to corrosion or erosion.

Corrosion gauges with their dual-element transducers are the primary inspection tool used to measure the remaining walls of components such as pipelines, pressure vessels, storage tanks, and numerous other applications..

The Digital Ultrasonic Thickness Gauge is an intelligent that adopts ultrasonic measuring principle. Controlled by micro processor, offers immediate and precise measurement of thickness for most of industrial material.  

 The measurement range of 1.20~225.00mm combined with ultrasonic wave velocity measurement function of 1000~9999m/s provides accurate measurement readings.Widely used in various precise measurements for different hardware/parts in industrial realm. One of its important applications is to monitor the level decreasing thickness during operation of various and pressure container.

 Diffusely applied in manufacture fields, metal processing as well as commercial inspection and can be applied for materials that conduct and reflect constant sonic velocity.


  • Auto Calibration to assure the accuracy
  • Auto linear compensation: this advanced software program enhances the precision by correcting the non-linear accuracy of transducer
  • Use upper and lower keys to make a quick adjustment for the sound velocity/thickness and a quick recall to the stored data
  • Coupling status indication: Observing the coupling icon to learn if the coupling is accomplished or not
  • 10 thickness measurement storage and recall function available, which facilitated the height work or working in wild area
  • Sound velocity measurement: with a given thickness by a sample hardware to measure the sound velocity, which avoid the further conversion or consultation of the table
  • 12 sound velocity for different material which also adjustable
  • Low battery indication
  • Auto power off mode designed to conserve battery life
  • More than 10000 times long life keys
  • The unit has a special memory that retains all of its setting even when the power is off
