Resolution 0.01mm Non Destructive Testing Equipment Ultrasonic Thickness Gauge with Software
Technical Data Download: iqualitrol Ultrasonic Thickness Gauge UM-4
Brief Introduction:
The innovative A scanning snapshot function marks the economic thickness gauge into digital age.
UM-4 first provides A scanning waveform display function in the similar products of other manufacturer. Ultrasonic is no longer an abstract conception, users could see the ultrasonic signal directly, to verify if the thickness reading is correct, analyze the cause of the problem and help users to find the solution of the problem.
The only real 0.01mm resolution of ultrasonic thickness tester in the similar products.
The display resolution of ultrasonic thickness is usually 0.01mm, but it's hard for the real resolution up to 0.01mm. Ordinary timing counter within the thickness gauge is generally below 30 MHZ. With the break through full digital technology and special algorithm, the true resolution of UM-4 can reach 0.01mm. Lots of experiments prove that it's easy for UM-4 to distinguish that thickness is only 0.01mm difference of two blocks.
Kindly Reminder: The instrument does not contain rubber sheath. if you need, please contact our online customer service.
Larger and More convenient storage capacity
Store 100,000 thickness values, 20 - 200 times of similar products.
We are the first adopt grid format storing files, one screen can display 15 thickness values, and according its position in grid, which is more convenient for the users to browse the thickness data.
USB 2.0 full speed connector.
Zero Cross Measurement Technology
Based on full digital technology, with zero cross measurement technology, the measured value will not be affected by echo intensity, material attenuation coefficient, gain and the height of gate, keep high measurement stability and reliability.
Update rate
Selectable 4Hz, 8Hz, 16Hz; 4Hz for ordinary application, 8Hz and 16Hz for more quick scan.
Easy Operation
UM-4 Series is a very simple operation instrument, users dont need any training to use.
More Practical Functions:
Gain: Adjustable High, Medium or Low
Alarm Mode: Dynamic change the color of thickness readings for alarming
Difference/Reduction Rate: Difference mode displays the difference between the actural value and the normal value. Reduction rate calculates and shows the percentage of the thickness reduction when the material become thin. Typical application is to measure the metal material which is due to bending and becomes thin.
Max./Min. Capture: On this mode, the current thickness, minimum thickness and the maximum thickness will be shown on the screen at the same time.
Multi-Language Available: Chinese, English, Japanese, French, German, etc.

Application of Ultrasonic Thickness Gauge
Ultrasonic thickness gauge is a widely used nondestructive test technique for measuring the thickness of a material from one side.
It is fast, reliable, and versatile, and unlike a micrometer or caliper it requires access to only one side of the test piece.
The first commercial ultrasonic gauges, using principles derived from sonar, were introduced in the late 1940s. Small, portable instruments optimized for a wide variety of test applications became common in the 1970s.
Later advances in microprocessor technology led to new levels of performance in today's sophisticated, easy-to-use miniature instruments.
1. What can be measured?
Virtually any common engineering material can be measured ultrasonically. Ultrasonic thickness gauges can be set up for metals, plastics, composites, fiberglass, ceramics, and glass. On-line or in-process measurement of extruded plastics and rolled metal is often possible, as is measurement of individual layers or coatings in multilayer fabrications.
Liquid levels and biological samples can also be measured. Ultrasonic gauge is always completely nondestructive, with no cutting or sectioning required.
Materials that are generally not suited for conventional ultrasonic gauge because of their poor transmission of high frequency sound waves include wood, paper, concrete, and foam products.
