Do your instruments require any formal training for use? Do you offer ‘demo’ models?
No. Our instruments are designed for simple operation, feature easy-to-use menus, both full and quick instruction manuals, and helpful videos. In lieu of demonstration models, we provide unlimited technical support via telephone and/or email, and a limited 30-day money back guarantee.
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 C 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?
Our PosiTector UTG ultrasonic wall thickness instruments are designed to accurately measure the wall thickness of carbon steel, aluminum, stainless steel and plastic.
PosiTector UTG probes utilize a 5MHz transducer. Like other UT (ultrasonic wall thickness) gages utilizing a 5MHz transducer, the PosiTector UTG is challenged to provide reliable wall thickness measurements on cast metals including iron, aluminum and zinc. The internal structure of the cast metal typically interferes with the transmission of a 5MHz sound impulse causing the gage to yield inaccurate thickness readings.
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 multi-echo probe disregards the exterior coating thickness on a painted metal structure and reports 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.
How often should the PosiTector probe be recalibrated?
PosiTector probes include a Certificate of Calibration with no expiry or end date. They have no shelf life, therefore the length of time in the field is not a good indicator for recalibration intervals. Many organizations with quality programs and recertification programs require annual recalibrations, and this is a good starting point for most users. Manufacturers recommend that customers establish calibration intervals based upon their own experience and work environment. Based on our product knowledge, data and customer feedback, a one year calibration interval from the date the instrument was placed in service is a good starting point.
No. Our instruments are designed for simple operation, feature easy-to-use menus, both full and quick instruction manuals, and helpful videos. In lieu of demonstration models, we provide unlimited technical support via telephone and/or email, and a limited 30-day money back guarantee.
