The PosiTector UTG® measures the wall thickness of materials such as steel, plastic and more using ultrasonic technology. Ideal for measuring the effects of corrosion or erosion on tanks, pipes or any structure where access is limited to one side. Multiple echo (UTG-ME) Thru-Paint models measure the metal thickness of a painted structure without having to remove the coating.

Step 2: Select Probe Style
Corrosion Probe
Measures the wall thickness of materials such as steel, plastic and more. Ideal for measuring the effects of corrosion or erosion on tanks, pipes, or any structure where access is limited to one side
- 5 MHz dual element transducer with wear resistant PEEK probe tip
- Automatic V-Path compensation for thin materials
- NEW UTG CX Xtreme probe with braided stainless steel cable and heavy-duty strain reliefs for demanding applications
Multiple-Echo Probe
Features Thru-Paint capability to quickly and accurately measure the metal thickness of a painted structure without having to remove the coating. The most accurate method to measure the remaining wall thickness of a painted structure because it automatically disregards the coating, lowering inspection time and expense. Also ideal for measuring on sandblasted materials or other applications requiring a durable wear face.

- 5MHz contact probe with wear resistant Alumina probe tip
- Multiple Echo technique averages 3 or more echoes for accurate and reliable readings
- Most accurate method to measure remaining wall thickness of a painted structure because it automatically disregards the coating, lowering inspection time and expense.
- Toggle easily between:
- Multiple Echo mode to eliminate coating thickness
- Single Echo mode to detect pits and flaws, and to increase the measurement range
The new PosiTector® UTG CX Xtreme corrosion probe features the same trusted and precise ultrasonic technology as the PosiTector UTG C probe with the addition of a robust braided stainless steel cable and heavy-duty strain reliefs. It is the direct result of inspectors’ requests for a probe that features the same accuracy and ease-of-use of the current PosiTector UTG C with additional ruggedness to handle even more demanding applications.
PosiTector UTG C & UTG CX Features:
- Braided stainless steel cable and heavy-duty strain reliefs for demanding applications (PosiTector UTG CX only)
