#ndt Innerspec launches a new line of Ultrasonic Thickness Gauges which require no liquid couplant. The new gauges use non-contact Electro Magnetic Acoustic Transducer (EMAT) and Dry-Coupled Ultrasonic Testing (DCUT) technology to provide thickness measurement on materials ranging from 1mm to 1m (0.040″ to 40″) with an accuracy of +/-2.54µm (+/-0.0001″). The non-contact EMAT ultrasonic technique permits one-side measurements at temperatures ranging from -30ºC to 650ºC (-22ºF-1202ºF), making it ideal for process
