| The PC Card Type Data Logger series consists of high performance data loggers which use a PC card as the data recovery medium. Data from several sensors can be recovered onto one PC card. All of the models can operate for a long time on lithium batteries or on an external power supply (conventional batteries or solar batteries). All operations are concentrated in 3 switches, so that even a beginner can easily operate the unit with little danger of making mistakes. Surge protection measures are taken on all external power supply terminals and sensor input sections which can serve as routes for surges to enter. |
