HP480 and HP481 Compressed Air: Relative Humidity Temperature and Dew Point Data Logger
|
Compressed air is often required to have a low humidity level. Measuring the dew point (DP) of water vapour in the compressed air that circulates in the system has many advantages. The HP480 and HP481 probes are designed specifically for this purpose.
