Defelsko Positector UTG

What is the difference between the PosiTector UTG C, PosiTector UTG M, and PosiTector UTG P probes?

The PosiTector UTG C Ultrasonic Thickness Gauge (Corrosion) single echo probe uses a dual-element transducer, a focused “V-path”, and V-path compensation to accurately measure the thickness of metals with heavy corrosion or pitting. The UTG C single echo probe will not ignore the thickness of the exterior coating: for best measurement accuracy, it may be necessary to remove any coating present at the point of measurement.

The PosiTector UTG M Ultrasonic Thickness Gauge (Multi-echo) probe uses a single element transducer to accurately measure the metal thickness of a new or lightly corroded structure while ignoring the thickness of protective coatings. The ultrasonic beam travels in a straight path to the material’s back wall at 90° relative to the surface. When three consecutive back wall echoes are detected, the probe makes a time-based calculation to eliminate the coating thickness from the gauge reading.

The PosiTector UTG P Ultrasonic Thickness Gauge (Precision) probe uses a single element delay line transducer to accurately measure the thickness of thin materials including plastics and metals. It automatically switches between single-echo or multiple-echo modes depending on material and thickness.
