The PF80 is a robust crack monitor that can be mounted on a structure (foundation, bridge, dam, viaduct, etc.) and can measure and record over 51,000 data logs (displacement, temperature, date and time) using proven technology and with up to 5-years of battery life. This high-resolution data can then be down loaded wirelessly or via a USB cable in CSV format for evaluation in a spreadsheet.
