The HT 225A Portable Concrete Test Hammer (HT225A) is designed specifically for the non-destructive testing of concrete structures. This method has considerable advantages over conventional methods of assessing the compressive strength of concrete in that large areas can be tested in a very short time at a very low cost. In addition, it is possible to determine the variation in concrete quality between different sections of a structure. The above standards refer to assessment of the rebound hardness of mortar which is directly related to the compressive strengths of the material being tested.

The SA40 Ultrasonic Wall Thickness Gauge is a hand held thickness gauge specifically designed for measuring the thickness of metallic, and non-metallic materials from one side where it is not possible to gain access to the other side. Materials that can be measured includes : aluminium, titanium, plastics, ceramics, glass and other good ultrasonic wave-conducting materials, as long as the material has parallel top and bottom surfaces. With uses in many areas of industry, the SA40 can perform precise measurements on various types of raw materials, component parts, and assembled machinery. It can also be used to monitor all types of pipes and pressure vessels for loss of thickness due to corrosion. The SA40 is very easy to use. After a simple calibration to a known thickness or sound velocity, the gauge will give fast and accurate readings in millimetres.
