Assessment of Insulation Gas gas leak detector

Assessment of Insulation Gas gas leak detector

Mainly used for picking up the high frequency (hissing) sounds generated by leaks from a pressurized system. Generally used for detection of gas leaks but can, in some situations, be used for liquid leaks as well. Pinpointing the areas where leaks occur can be time consuming and very costly. These ultrasonic tools are designed to save you time and increase the accuracy in locating even the smallest
