Pipecheck 2 is a simple-to-operate hand-held instrument that will positively identify pipes filled with water. It is designed to address the major identification problem experienced by engineers engaged mostly in the Water and Gas service industries, when old cast or spun iron pipes are exposed.

Pipecheck uses an ultrasonic pulse-echo technique to indicate that a pipe contains water. When its probe is in contact with a pipe, an ultrasonic signal is transmitted into the pipe wall. This causes a series of standing echoes to develop. If the pipe is full of water, and certain criteria are satisfied, some of the ultrasound travels across the internal diameter of the pipe and returns, by the same path, to trigger the Water response. 

If the pipe contains gas or other contents the sound remains within the pipe wall and a red light is triggered. Similarly if the pipe is heavily corroded, but contains water, then the red light still may trigger. For this reason it is always recommended that a pipe is tested several times in different places.

Pipecheck 2 is a microprocessor controlled instrument housed in a rigid injection moulded plastic case, with front panel membrane ensuring environmental protection to IP65.
