Mitech standard ultrasonic thickness probe N05/90°, suitable for Mitech all line ultrasonic thickness gauges, it is the standard configuration of MT150, MT160 and MT200. The standard ultrasonic thickness probe N05/90°with frequency of 5MHz, crystal size of 10mm, its measuring range for common ultrasonic thickness gauge is 1.0-230mm in steel while its measuring range for multi-mode ultrasonic thickness gauge is 1.0-600mm in steel. The cable length of the N05/90° probe is 90cm and its limitation for the minimum pipe diameter is Φ20mm×3.0mm. Mitech N05/90°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.
