C. power and is equipped with nine input channels and nine sampling time-periods. A replaceable memory cartridge used in this data logging system is a special feature that makes data recording easy either in a mobile (short-term) observation or in a fixed-point (long-term) operation.The specially designed memory cartridge also makes the collected-data easy and convenient for process when it is linked up with a personal computer.
