than their commercial counterparts. Campbell Scientific recommends the use
of industrial-grade cards, such as the CFMC2G (FIGURE 4-6) available from
Campbell Scientific. For more details about this card, see Application Note
3SM-F, CF Card Information, available from www.campbellsci.com .
USB Memory Card Reader/Writer: The 17752 USB memory card
reader/writer, shown in FIGURE 4-9, is a single-slot, high-speed reader/writer
that allows a computer to read a memory card. When used with Campbell
Scientific equipment, the 17752 typically reads data stored on CompactFlash ®
cards, but it can read many different types of memory cards. The 17752
connects to the computer's USB port.

Temperature Probes: The AP200 system can measure a temperature profile
at up to eight levels, using 107-L temperature probes. The 107 is a rugged,
accurate probe that measures air temperature from –35°C to +50°C. The "-L"
denotes that the cable length is specified at the time of order.
Radiation Shield: Each 107-L temperature probe is normally mounted with a
41303-5A radiation shield. The 41303-5A is a naturally aspirated, six-plate
radiation shield. Its louvered construction allows air to pass freely through the
shield, serving to keep the probe at or near ambient temperature. The shield's
white color reflects solar radiation.
The temperature probe with its accompanying radiation shield is shown in
FIGURE 4-10.
