A thickness gauge is a precision instrument used to measure the thickness of materials, often in industrial settings. These gauges can be mechanical or electronic and are typically made from durable materials such as metal or high-impact plastic. They work by using various measurement principles, including ultrasonic, magnetic induction, or mechanical contact methods, to provide accurate readings of material thickness.
| Measurement range | 0.1 mm to 200 mm |
| Accuracy | ±0.1 mm to ±0.5 mm |
| Display type | Digital or analog |
| Power source | Battery-operated or rechargeable |
| Operating temperature | 0°C to 50°C |
| Material compatibility | Metals, plastics, coatings, and more |
| Calibration | Factory calibrated with options for field calibration |
When selecting a thickness gauge, consider the material types you will be measuring, as different gauges are designed for specific materials. Check for accuracy specifications and ensure the gauge meets your required tolerances. Additionally, consider the operating environment and whether a digital or analog display is preferable. Request information on calibration certificates and available grades to ensure compliance with industry standards.
