DAT instruments, JET SDP

JET SDP records several parameters depending on connected sensors (pressure, inclination, speed, rotation, etc…). Data are displayed in real time on the LCD monitor and recorded on internal memory. Afterwards, all recorded data are downloaded to a PC in order to file them and to print graphics.
