The PX-7 Precision Thickness Gauge has a measuring range from 0.0060 to 1.0000 inch, (0.15 to 25.40 mm). Using a single element delay tip transducer, the gauge will measure very thin materials in the Echo-to-Echo Mode and automatically switch to Interface Echo Mode when measuring thicker materials and plastics. In the Echo-to-Echo Mode you have the ability to measure the thickness of materials without removing the paint or the coating.
THE PX -7 utilizes state-of -the-art digital technology to produce fast and accurate readings. It is packaged in an all-aluminum sealed case making it resistant to the working environment. The gauge is simple to operate and features: Alarm Mode, Differential Mode, Internal Data-Logging and an RS-232 data output port to interface with a computer or other data acquisition system.
