1.1 Product Description
The 27MG instrument is a handheld ultrasonic thickness gage designed for a wide
variety of thickness-measurement applications. With the 27MG, you only need access
to one side of a part in order to obtain nondestructive measurements of the thickness
of corroded, pitted, granular, and other difficult materials.
The 27MG operates with dual element transducers and can measure material
thicknesses between 0.50 mm and 635.0 mm (0.020 in. and 25.0 in.). The temperature
range of measured materials may vary between −20 °C and 500 °C (−4 °F and 932 °F),
depending on the material’s characteristics, the transducer, and the measurement
mode.
Basic features
• Measurement-related status flags and alarms
•LED back-lite display
• Automatic probe recognition for the standard D79X and MTD705 transducers
