Air Cooling
All 973 systems are equipped with air cooling. When air cooled, the fan speed is controlled
automatically by the computer. Air cooling is generally sufficient for measurements of frost/dew
points from approximately –50 to +20°C. Air cooling operates automatically and requires no
user input.
Water Cooling
The 973 is not equipped with any provisions for water cooling.
