F.A.Q

Is the PosiTector UTG calibrated at the factory?

The PosiTector UTG arrives fully calibrated and ready to measure. A Long-Form Certificate of Calibration traceable to NIST is included, which documents actual readings taken by your instrument at our calibration laboratory on standards traceable to a national metrology institute. Beware of ‘Certificates’ or ‘Certificates of Conformance’ offered by competitors. These typically do not include actual instrument readings, and are often insufficient to meet common quality requirements.

Verification of gage calibration and accuracy can be performed with the accessory Certified Step Block. If necessary, the PosiTector UTG operator can easily perform a calibration adjustment to align the gage’s thickness readings to match that of a known reference sample.

Can I measure the thickness of non-metallic materials like plastic and rubber with the PosiTector UTG?

Yes! The PosiTector UTG features several preprogrammed sound velocities for common materials. For best accuracy, make a simple adjustment to a known sample thickness of the material or quickly enter the material’s sound velocity into the gage. The PosiTector UTG can be adjusted to a broad range of sound velocities spanning from 0.0492 to 0.393 mils/µs (1250 to 10000 m/s).

Can the PosiTector UTG measure cast/ductile iron or cast aluminum?

Yes. The PosiTector UTG CLF probe was designed to measure attenuative materials such as cast metals including iron, aluminum and zinc.

What is the difference between the PosiTector UTG C and PosiTector UTG M?

The PosiTector UTG C (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 particularly 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 (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 gage reading.

If there is paint on the surface and it can’t be removed, can the PosiTector UTG C be used?

Yes, but coatings such as paint have a slower sound velocity than metal. This means that coating ‘appears’ much thicker to the instrument than it actually is, and can substantially affect the reading. Using Thru-Paint technology, the PosiTector UTG M and PosiTector UTG P probes disregard the exterior coating thickness on a painted metal structure and report only the metal thickness.

Can the UTG measure the thickness of materials with heavy corrosion on the back/inside?

The PosiTector UTG C (Corrosion) is a proven solution for measuring the thickness of metal structures with pitting and/or moderate-to-severe corrosion on the back wall.

What are the available probe options?

PosiTector UTG CA / UTGC – dual element, single-echo probe ideal for measuring severely corroded/eroded materials. PosiTector UTG CA models feature a built-in probe, while PosiTector UTG C models feature a probe mounted on a 1m (3ft) cable.

PosiTector UTG CX – same specifications as UTG C above, but includes a braided stainless steel cable jacket and reinforced strain reliefs for protection in demanding environments.

PosiTector UTG CLF – dual element, single-echo probe designed for measuring thick and/or attenuative materials such as cast iron.

PosiTector UTG M – single element, multiple-echo probe features Thru-Paint capability designed to quickly and accurately measure the metal thickness of a painted structure without having to remove the coating.

PosiTector UTG P – single element probe with automatic multiple-echo or single-echo mode depending on material type and thickness, can be used for Thru-Paint applications. Ideal for high-resolution measurements on thin plastics and metals.
