JJF 1126-2004 《Calibration Specification for Ultrasonic Thickness Instruｍents》 Related products

The JF 1126-2004 standard provides a calibrated specification for Ultrasonic Thickness Gauges with resolutions of 0.1mm and 0.01mm. This specification is suitable for thickness measurement of ship hulls, oil and gas pipelines, high voltage vessels and large area plates, etc. It is suitable for metallic and Non-metallic materials. Ultrasonic Thickness Gauges emit ultrasonic waves through the probe and measure the time it travels through the material to calculate the thickness of the measured object. The standard defines the resolution, Measurement range (0.5mm200mm), Speed of sound range (1000m/s9999m/s) of Ultrasonic Thickness Gauge, and refers to relevant literature such as "General Measurement Terms and Definitions" and "Measurement Uncertainty Evaluation and Representation". The specification ensures the measurement accuracy and conformity of the thickness gauge.
