The c CF-4H-950F oupling fluid is a high temperature coupling fluid for ultrasonic wall thickness gauges. It enables accurate measurements on surfaces with an recommended temperature range from 316ºC to 404 ºC.
It provides coupling for high-temperature thickness gauging and will maintain acoustic coupling at high temperatures beyond 15 seconds to give ample time to obtain thickness readings. In most cases, the signal strength increases with time to the point of the couplant’s thermal decomposition.
