DAT instruments, JET DSP 100

JET DSP 100 datalogger records several parameters depending on version and connected sensors:

  • IR version, for Lugeon tests, Permeability tests, Grouting (pressure, flow-rate, volume, time, duration);
  • D version, for Diaphragm walls and Hydromills (depth, speed, inclination, deviation, rotation, time, duration).

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.
