This product is an intelligent ultrasonic thickness gauge that adopts the latest high performance and low power consump�on microprocessor technology. Based on the principle of ultrasonic measurement, it can measure the thickness and sound velocity of metal and other materials. It can detect the thinning of pipes and pressure vessels a�er corrosion, and can make accurate measurements of plates and machined parts. The gauge can be widely used in petroleum, chemical, metallurgy, shipbuilding, avia�on, aerospace and other fields. ● 3.7V 2000mAh lithium ba�ery ● Auto calibra�on ● 300 groups of data storage ● High sensi�ve probe ● Buzzer alarm ● Mul�ple materials selec�on Specifica�ons Display Measurement range Sound velocity range Unit Accuracy Lower limit of pipe measurement Data storage 300 groups, including material, sound velocity, unit, measured value, MAX, MIN and AVG of each group Main func�ons Single measurement, con�nuous measurement, alarm, sound velocity measurement, auto calibra�on Charging specifica�on Opera�ng �me (full ba�ery) Opera�ng temperature and humidity Storage temperature and humidity General Characterisi�cs Ba�ery Product size
