The Mitech high temperature couplant GW-II is one of the optional configuration for Mitech series of ultrasonic thickness gauges. The high temperature couplant GW-II, suitable for couplanting between the high temperature probe and the tested workpiece under the temperature lower than 300 ℃, compared with the common couplant, the high temperature couplant with higher heat resistance, it will not produce the smoke during using, more health and environmental, not easy to freeze and flush, capable of ensuring the normal propagation of the ultrasonic signal between the probe and the tested material under high temperature situation to realize the precisely measurement, it is the necessary accessory for thickness measurement under high temperature. It is recommended to use on the probe when do measurement under higher temperature.
