CFM100 Compact Flash Module
There are two types of CF cards available today: Industrial grade and Standard or
Commercial grade. Industrial grade PC/CF cards are held to a higher standard;
specifically they operate over a wider temperature range, offer better vibration and
shock resistance, and have faster read/write times than their commercial
counterparts (Table B-3). The Industrial Grade cards more closely match the
operating envelope of the dataloggers, and for this reason we recommend you
always use extended temperature tested, Industrial Grade PC/CF cards with a
datalogger.

All Campbell Scientific products are Electrostatic Discharge (ESD) tested to
ensure that in the event of a static discharge neither the equipment nor the data is
damaged or lost. Campbell Scientific ESD tested several brands of cards, only the
Silicon Systems cards passed this testing. Campbell Scientific recommends that
only Silicon Systems cards be used with Campbell Scientific CRBasic
dataloggers. It is not necessary to purchase the cards directly from Campbell
Scientific, as long as the Silicon Systems card model number matches Table B-4.
