PosiTector UTG

What is the measuring accuracy of the PosiTector UTG?

The accuracy depends on the model. Standard $\text{UTG C}$, $\text{M}$, and $\text{CLF}$ probes offer an accuracy of $\pm 0.03\text{ mm}$ ($\pm 0.001\text{“}$), while the $\text{UTG P}$ (Precision) probe provides a higher accuracy of $\pm 0.01\text{ mm}$ ($\pm 0.0004\text{“}$).

What does the Advanced Model offer over the Standard Model?

Advanced Models provide significantly more memory ($\text{250,000}$ readings in batches), $\text{WiFi}$ and $\text{Bluetooth}$ connectivity, $\text{A}$-Scan and $\text{B}$-Scan capabilities, Prompted Batch Mode, and live graphing on the gauge.

Does the PosiTector UTG require calibration before use?

No, the PosiTector UTG arrives fully calibrated and ready to measure with an included $\text{NIST}$ or $\text{PTB}$ traceable Long Form Certificate of Calibration. Verification can be performed using an accessory Certified Step Block.

How does the $\text{UTG M}$ (Multiple Echo) probe measure metal thickness under paint?

The Multiple-Echo technique measures the time between consecutive back wall echoes from the metal. By measuring multiple echoes, the gauge calculates the metal thickness only and effectively cancels out the slower velocity signal from the coating thickness.

Can the UTG series be used for sub-surface flaw detection?

While primarily a wall thickness gauge, the Advanced Models with their $\text{A}$-Scan feature allow users to analyze the ultrasonic waveform. This can be used to visually identify sub-surface flaws or inclusions by observing intermediate echoes within the material.
