What sets SOFREL LT data loggers apart from other products on the market is the performance of their antenna and reliability of transmissions. Further more, the LT comes with software to test GSM coverage for each operator, enabling the optimal installation location to be identified                                                 

Every day, LT data loggers transmit recorded data and balances to central systems. Communications
to central PCs or directly to the mobile phones of duty personnel can be set up for certain events (threshold exceeded, manhole cover opened, etc.).
