Compact & Precise Ultrasonic Thickness Gauge for Challenging Access Points

The Sauter TD-US Ultrasonic Thickness Gauge is a lightweight, pocket-sized device ideal for measuring material thickness where access is limited. Suitable for metals, plastics, ceramics, and composites, this gauge provides fast and reliable readings up to 225 mm with a resolution of 0.1 mm. Its compact form factor makes it an ideal tool for maintenance engineers, inspectors, and technicians working in tight or elevated spaces.

Equipped with a high-frequency 5 MHz external probe and RS-232 interface, the TD-US ensures accurate measurements and easy data transfer. Delivered in a protective carrying case, it includes everything required for immediate use, including contact gel and batteries.
