1-8 | 5830 Moisture Analyzer
While the frost-point temperature will be higher than the dew point
temperature, the exact magnitude of the difference will be a function
of both the pressure and dew/frost point temperature.
Another consideration, when using the 5830 analyzer to calculate dew/
frost point temperatures, is the sample or process pressure. The range of
process pressures allowed by the Model 5830 is restricted for many sample
gases. Many gases liquefy at relatively low pressures, so calculating a dew/
frost point temperature for these compounds has no value. Therefore, the
5830 is designed to report an error condition, the process pressure alarm,
to alert the user to conditions that result in ambiguous dew/frost point
values.
