The “Smart-Link Live” application meets the growing demand for tracking and traceability. It allows the user to keep their eyes on the target while data streaming from the LZ-30 is captured within the application. The application logs date, time, GPS coordinates and gas measurements. Sessions can be exported from the phone/tablet in multiple formats. With built-in picture capture, the user can associate any reading with a picture or even report a corrosion issue.
