steel thickness meters
Description
Application:Our ultrasonic thickness gauge possesses a number of advantages-strong measuring capacity, fine linearity, high precision, good stability and easy operation. Free from temperature and time drift, it has very little deviation of thickness reading. Used for measuring thickness and corrosion of pressure vessels, chemical equipment, boilers, oil storage tanks, etc. in industries of petroleum, shipbuilding, power station, and machine manufacture.
Have backlit display for dim or dark environments.
Operating principle: Interfacial wave ~echo mode (normal mode)
Echo ~echo mode (precise mode)
