The micro-diameter ultrasonic thickness probe N07, suitable for Mitech all line ultrasonic thickness gauges, it is the standard configuration of MT660. The micro-diameter ultrasonic thickness probe N07 with frequency of 7MHz, crystal size of 6mm, suitable for the measurement of thin wall and small arc surface, its measuring range for common ultrasonic thickness gauge is 0.75-80mm in steel while its measuring range for multi-mode ultrasonic thickness gauge is 0.65-200mm in steel. The cable length of the N07 probe is 90cm and its limitation for the minimum pipe diameter isΦ15mm×2.0mm. Mitech N07 probe, elaborately developed with material of piezoelectric ceramic, engineering plastic and stainless steel, integrated die casting process and splinting probe design for convenient plugging, it can effectively reduce the fault caused by frequent plugging, accurate and durable. It is widely used for monitoring the corrosion thinning degree for various pipelines and pressure vessel of the manufacturing devices in petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace and other fields. It also can be used to make accurate measurement for various plants and mechanic parts.
