The gauge case materials are made of either ABS or 300 series of stainless steel. The Bourdon tube is constructed of inconel, a highly elastic material with corrosion resistance. The balance of the gauge hardware is designed to minimize corrosion associated with challenging field environments. Our CA7024 cable tester is a hand-held, alphanumeric, TDR (time domain reflectometer) cable length meter, and fault locator. It is designed to measure the length of electrical and communication cables. It can also indicate the distance to a fault in the cable.
