The Defelsko PosiTector UTG C1 Ultrasonic Wall Thickness Gauge is an ultrasonic Thickness Gauge designed to measure the wall thickness of materials such as steel, plastics, and other materials measured with ultrasonic technology.Ideal for measuring structures such as tanks, pipe walls, etc., that are only measurable on one side and are affected by corrosion or erosion.The UTG C1 Ultrasonic Wall Thickness Gauge is:The standard model of the PosiTector UTG C series has 250 measurement reading storage and measures thickness ranging from 1~125mm.




1) 5 MHz dual-element sensor with wear-resistant PEEK probe tip
2) Automatic V-way compensation for thin materials

1. High-resolution color LCD screen
2. With 250 data storage memory, the stored readings can be viewed or downloaded
1. Simple
Large and easy-to-read graphic LCD display
Easy-to-use, one-handed menu navigation
Pre-set speeds – simply select from a list of common materials or easily enter them yourself
Smart Couple™—eliminating inadvertent decoupling—is an excellent choice for analyzing large areas using multiple channels
Flash indication – suitable for noisy environments
The reset function enables an immediate factory reset
2. Durable
Weather-resistant – resistant to solvents, acids, oils, water and dust
Impact-resistant lenses
Abrasion resistant probes
Shock-absorbing, protective leather case with clip rubber
The main unit and probe are guaranteed for two years
3. Accurate
Precision ultrasonic sensors provide fast, accurate readings
The calibration certificate (long) shows traceability to NIST
Compliance with national and international standards, including:ASTM e797
Built-in temperature compensation ensures measurement accuracy
4. Multi-purpose
The Positector mainframe is compatible with all PosiTector 6000, 200, DPM, UTG, RTR, and SPG probes, making it easy to convert from a layer Thickness Gauge to a dew point, surface profiler, or ultrasonic wall Thickness Gauge.
Single-point or two-point calibration
Inch/mm unit conversion
Multi-language options are available
Inverted display
Lithium or rechargeable batteries (including chargers)
5. Powerful
Minute scans – measurement rates up to per second20 pcsreading
Statistics - Continuously display/update the number of averages, standard deviations, min/max thicknesses and thickness readings
Measurements that exceed user-specified limits will occurHiLo alarm sounds and visible alarms
Each is stored with a date and time stamp of the measurement
The USB port provides quick and easy connection to a PC and provides continuous power, including a USB cable
The software consults, analyzes, and reports on data
