Introduction
LK390 ultrasonic Thickness Gauge is launched by our company in strict accordance with DB 37/T1846-2011 Thickness Gauge standard and JJF 1126-2004 "Ultrasonic Thickness Gauge Calibration Specification". It has many advantages such as small size, light weight, low power consumption, etc., and has the advantages of small size, low power consumption, strong penetration, anti-beating, anti-vibration, stable indication value, and high detection accuracy (display accuracy ± 0.001 inch or ±0.01mm), and is a satisfactory testing tool for non-destructive testing workers.
When the ultrasonic pulse emitted by the transducer passes through the measured object to the material interface, the pulse is reflected back to the probe, and the thickness of the measured material is determined by accurately measuring the time of ultrasonic wave propagation in the material. It can accurately measure plates and machined parts of various materials; Various pipes and pressure vessels in production plants can be monitored to detect the degree of thinning due to corrosion during use. The instrument can be applied to measure the thickness of hard materials, such as steel, stainless steel, aluminum, copper, chromium alloy and other metal materials, and plastic, rubber, ceramics, glass and other non-metals. The instrument is widely used in petroleum, chemical industry, electric power, boiler, metallurgy, shipbuilding, aviation, aerospace and other fields.
