We are British manufacturers of ultrasonic technology operating in 120 countries (pictured here in Iceland!)

Our mission is to help you deliver the Safesite® and Safeship®.

This means we aim to improve safety for people, assets and infrastructure on land and at sea worldwide across diverse sectors.

We do this through our products which focus on liquid level indication, seal integrity, thickness gauging, flow rate monitoring and bearing indication.

For the last 30 years we designed handheld, reliable, accurate portable inspection products. In 2020 after listening to our customers we will move to constant monitoring systems.
