ZB N 77001-1989 《General Technical Conditions for Ultrasonic Thickness Gauge》 Related products

"ZB N 77001-1989 Ultrasonic Thickness Gauge General Technical Conditions" mainly stipulates the technical requirements and inspection methods of the pulsed reflection Ultrasonic Thickness Gauge with digital display. The standard includes many technical requirements such as Measurement range, error limit, measurement of flat bottom hole capacity, and lower limit of pipe wall thickness measurement. The thickness gauge should be suitable for battery power supply and carry out environmental testing in accordance with the GB6587 series standard. In addition, the standard also requires the thickness gauge to have stable indication and stable performance under voltage changes, as well as temperature resistance, moisture resistance, vibration resistance and Impact resistance to adapt to different working environments. The product standard also includes provisions on the thickness gauge's Appearance mass, electrical structure requirements and sound speed adjustment range to ensure accurate measurement and stable performance.
