Relative Humidity Measurement
Relative Humidity is the measure of the amount of water vapor in the air at a particular temperature, compared with the total amount of water vapor the air can hold at that temperature. The dew point is defined as the lower temperature to which air must be cooled in order for condensation to occur. The dew point is dependent on the concentration of water vapor present, and therefore on the relative humidity. These instruments will record both the humidity and dew point.
     The Sekonic Thermo-Hygrographs  are designed for long term recording from local or remote sensors. The ST-50 has a single Humidity/Temperature sensor.

The ST series thermographs are ideal for monitoring the environment in a wide range of applications and industries including food, pharmaceutical, semiconductor, chemical, museums, printing, paper mills, film production, hospitals warehousing and more.
