Rockwell Hardness Testers

Economical and easy to use, the UTG-1500 is a "World-Class" microprocessor controlled Ultrasonic Thickness Gauge. Currently our entry-level model, these ultrasonic thickness gauges are designed for measuring thickness of metallic and non-metallic materials, as long as the top and bottom surfaces are parallel. Utilized in many different areas of industry, the UTG-1500 Ultrasonic Thickness Gauges can perform precise thickness measurements on various types of raw materials, component parts, and assembled machinery. Ultrasonic Thickness gauges are also often used to monitor all types of pipes and pressure vessels for loss of thickness due to corrosion.

The UTG-1500 Ultrasonic Thickness Gauges are simple to calibrate, using a built-in standard, and the gauge will produce accurate and precise readings in inch or millimeter to .001"/.01mm.
