You can buy one a medical supply store or at a drug store or at least some of them sell them. You can also check out these sites I found for you to look at en.wikipedia.org/wiki/Ultrasonic_thickness_gauge , www.olympus-ims.com ... Handheld Thickness Gages
An ultrasonic thickness gauge is required for measuring the thickness of different types of materials. The best ultrasonic thickness gauge you can buy is the Defelsko Corporation Ultrasonic Thickness gauge.
I found some sites that can help you find out how much one of these meters should cost you to buy them. Here are the sites for you to have a look at www.advanced-ndt.co.uk/Thickness_Gauges.html
An ultrasonic flow meter is used to determine how fast a fluid is moving. Ultrasonic flow meters can be purchased on the internet from ZORO Tools, Northern Tool, and Grainger Industries.
Ultrasonic gauges need to be replaced every couple of years depending on how many times they are used. They are easily replaced so why not do it when you feel their usefulness is done.
An ultrasonic thickness gauge outputs ultrasonic waves which are reflected off a base surface. The resistance caused by the "coating layer" is measured by the magnitude of the returned waves. This resistance is used to determine a thickness measurement.
Your best bet would be to buy a used cheap ultrasonic thickness wall gauge on ebay or amazon.com You can also look at ones ranging from 1000-2000 dollars at http://www.instrumart.com/ProductList.aspx?CategoryID=5754&Landing=1&s_kwcid=TC|23075|ultrasonic%20thickness%20gaugeS|e|7537765444&gclid=CM_ZmLrwyKoCFcPBKgoddi8w2A
The best way to measure thickness is to use an ultrasonic transducer. You use the back reflection to figure out the thickness.
You can measure the thickness with an optical microscope (look at a crossection) or an ultrasonic probe.
Yes.
I would like to buy a paint meter to show the thickness of the paint on my automobile. Can you buy these in any retail stores?
I looked this up on line for you to have a look at, I hope these sites can help you. www.sonoguide.com/soft_tissue.html , www.yale.edu/ynhti/curriculum/units/1983/.../83.07.05.x.html
Ultrasonic thickness gauges are used in several industries. Gauges are available to test the thickness of metal, glass, ceramic, plastic and concrete so are common in any field which works with these substances.
