elcometer-205-206-and-206-dl-ultrasonic-thickness-gauges-200

The Elcometer 205, 206 and 206 DL Ultrasonic Thickness Gauges gives you a range of 3 robust, hand held gauges allows you to make reliable measurements or scan a length of material for defects or the thinnest point using the scan mode.Each gauge comes with 3 calibration options: single point, 2 point and speed of sound selection – allowing accurate measurements on a wide range of materials. Compatible with a wide range of measurement transducers, these ultrasonic thickness gauges are available with or without memory and all come with a backlight for measuring in darkened environments.

Measurement Modes:

  • Scan Mode:Measuring up to 16 readings per second, the gauge captures the minimum recorded thickness.
  • Alarm Mode:Once a minimum acceptable thickness has been set, a red LED illuminates and a buzzer sounds if a measurement falls below the preset value.
  • Differential Mode: Set an acceptable thickness (nominal) value in the gauge and the unit will display the positive or negative (±) difference from the nominal value entered.

Sound Velocities

Sound Velocities / Speed of Sound in Materials for Ultrasonic Thickness Gauges

The Ultrasonic Thickness Gauges can be programmed by the user to the appropriate Material in two ways :

  • Using known standards of the same material – set the calibration to the thickness
  • Using the Frequency calibration, set the frequency to the appropriate Material using the Velocity / Speed of Sound Chart below.
