Thickness gauges for wholesale on Tool.com are suitable for daily operation and strict laboratory measurement, and the operation is very simple and convenient. The ultrasonic thickness gauge uses the latest high-performance, low-power microprocessor technology, based on the principle of ultrasonic measurement, can be used to measure the thickness of metals and other materials, and can measure the speed of sound of materials. In addition, it can also measure the thickness of various pipes and pressure vessels in the production equipment, as well as accurately measure various plates and various processed parts. The coating thickness gauge mainly uses the principle of magnetic induction or the eddy current measurement to measure the thickness of the non-magnetic coating on the magnetic material. Coating thickness gauges are convenient and quick to measure, and have small measurement errors and high reliability. They can ensure the quality of products when they are coated, so they are widely used in machining and testing industries.
So there are certain differences between ultrasonic thickness gauge and coating thickness gauge, you need to pay attention to the following tips when you buy them online.
Ultrasonic Thickness Gauge vs. Coating Thickness Gauge
Type |
Ultrasonic Thickness Gauge |
Coating Thickness Gauge |
Working Principle |
According to the propagation time and speed of ultrasonic in the specimen |
Eddy current/ Magnetic induction |
Measuring Range |
0.5-600mm |
0-1250μm (Standard F1/ N1 probe) 0-10000μm (Optional F10/ N10 probe) |
The measuring unit of ultrasonic thickness gauge is mm. The measuring unit of coating thickness gauge is micron. 1mm=1000μm. |
||
Application |
It can monitor the thinning degree of various pipelines and pressure vessels in production equipment after being corroded during use. It is widely used in various fields such as petroleum, chemical industry, metallurgy, shipbuilding, aviation, aerospace, etc. The value of ultrasonic thickness gauges lies in non-destructive testing of thickness, which cannot be achieved by ordinary thickness gauges. |
The detection range of 0-10mm can meet the requirements of different industries for the thickness detection of electroplating, paint layer, enamel layer, aluminum tile, copper tile, Babbitt alloy tile, phosphating layer, paper, etc. It can be widely used in manufacturing, metal processing, chemical industry, commodity inspection and other detection fields, is a conventional necessary professional precision instrument. |
Measurement Conditions |
Coupled measurement |
Direct measurement |
Display Accuracy (Resolution) |
0.1/ 0.01mm swappable |
0.1μm (F1/ N1 probe) |
Readout Accuracy |
±0.5%H (H is the actual thickness of the measured object) |
±3%H |
The indication accuracy shows the accuracy of the real measurement (error). The display accuracy is the exact number of digits that can be displayed after the decimal point. |
