Casella CEL Thermohygrograph deluxe model - Manual (Page 3)

1. INTRODUCTION
This handbook introduces you to the basic operation and features of the
CASELLA deluxe THERMOHYGROGRAPH.
Thermohygrographs are used to produce a continuous record of the variation
of both the temperature and relative humidity of the atmosphere against
time, by drawing coloured traces on a chart.
Variations in relative humidity can affect many manufacturing processes,
storage of raw materials, weights of items such as wool, paper, tobacco,
confectionery, and computer operation, as well as being an important factor
in human comfort. Since temperature is often linked to changes in relative
humidity, this instrument records both on a single chart.
The THERMOHYGROGRAPH deluxe model may be ordered with or without a
calibration certificate.
