Final answer:
The chilled mirror/dew point method is a technique used to measure the dew point temperature of a gas or air sample. It offers high accuracy and precision, and does not require calibration gases or complex calculations.
Step-by-step explanation:
The chilled mirror/dew point method is a technique used to measure the dew point temperature of a gas or air sample by using a mirror whose temperature is below the dew point temperature. When the mirror is cooled, moisture in the sample will condense on its surface, forming dew. By monitoring the temperature of the mirror when dew forms, the dew point temperature can be determined.
One advantage of the chilled mirror/dew point method is its high accuracy and precision. This method provides reliable and repeatable measurements, making it suitable for critical applications where precise dew point temperature control is required.
Another advantage is that this method does not require any calibration gases or complex calculations. It relies on the physical phenomenon of dew formation, making it a straightforward and easy-to-use technique.
