The TM-8812 is a handheld microprocessor-controlled ultrasonic thickness gauge specifically designed to measure the thickness of metallic and non-metallic materials e.g. aluminium, titanium, plastics, ceramics, glass, plastics and other good ultrasonic wave conductors, as long as they have parallel top and bottom surfaces. This gauge can be used to determine the exact thickness of pipework to ensure the correct settings on an ultrasonic flow meter. The TM-8812 will check a pipe for loss of thickness ...
