1 Overview
The Model TU-US is a digital ultrasonic thickness gauge.
Based on the operating principles as SONAR, it is capable of measuring the thickness of various materials with an accuracy as high as 0.01 mm (or 0.001 inches).
It is suitable for a variety of metallic and non-metallic materials.
1.1 Product Specifications
Display: 128x64 dot matrix LCD with EL backlight
Measuring range: 0.75 to 300mm (in steel)
- TU 80-0.01, TU 230-0.01 US, as well as TU 300-0.01 are
measuring continuously with a resolution of 0.01
Sound velocity range: 1000 to 9999m/s
Resolution: 0.1/0.01mm (selectable)
Accuracy: ± (0.5% thickness +0.04) mm, depending on materials and conditions
Units: Metric/ Imperial units selectable
- Four measurements readings per second at single point measurement and ten
per second at Scan Mode.
- Memory up to 20 files (up to 99 values for each file) of stored values
- Upper and lower limits can be pre-set. It will alarm automatically if the
Measurement result exceeds the limit.
- Case: Extruded aluminium body suitable for use under poor working
conditions
Power supply: 2x AA, 1.5V alkaline batteries

H
- Capable of performing measurements on a wide range of materials including metals, plastic, ceramics, epoxies, glass and other ultrasonic wave well- conductive
materials.
- Four transducer models are available for special applications included coarse
grain material and high temperature applications.
- Zero adjustment function
- Sound velocity calibration function
- Two- point calibration function
- Two measurement modes: Single point mode
Scan mode
- Coupling status indicator showing the coupling status
- Battery indication indicates the rest capacity of the battery
- “Auto sleep” and “Auto power off” function to conserve battery’s life
1.3 Measuring principle
The digital ultrasonic thickness gauge determines the thickness of a part or a structure
by accurately measuring
The time required for a short ultrasonic pulse generated by a transducer to travel
through the thickness of the material, to reflect from the back or inside surface and be
returned to the transducer. The measured two-way transit time is divided by two to
account for the down-and-back travel path, and then multiplied by the velocity of sound
in the material. The result is expressed in following relationship:
Where: H ----˃ thickness of the test piece
v ----˃ sound velocity in the material
t ----˃ the measured round-trip transit time

Indicates the coupling status. While measurements are performed, this symbol should
be on. If it isn’t, the instrument is having difficulties in achieving a stable measurement
and the thickness value displayed will most likely be erroneous.
