Dew Point
The dew point is the temperature at which air becomes saturated and water vapour begins to condense, critical for preventing product damage.
What is Dew Point?
The dew point is the temperature at which air becomes fully saturated with water vapour (reaches 100% relative humidity) and condensation begins to form on surfaces. If the temperature of a surface drops below the dew point, moisture will condense on it.
Dew point is calculated from the combination of temperature and relative humidity readings. Many modern cloud monitoring platforms calculate and display dew point automatically from dual-parameter (T+RH) data loggers.
Why It Matters
Condensation is a major risk in cold chain environments. When warm, moist air enters a cold storage area, condensation can form on products and packaging — causing label damage, corrosion, mould growth, and product contamination. Monitoring dew point helps facility managers prevent condensation events before they cause damage.
Frequently Asked Questions
How is dew point calculated?
Dew point is calculated using the Magnus formula from temperature and relative humidity readings. If you have a data logger that measures both temperature and humidity, the dew point can be computed automatically by the cloud platform.
