Table 3-1a Dew point temperatures in Celsius or Centigrade.
Dew Point Table °C
Dew point
The dew point table provides dew point temperatures for a range of air temperature and relative
humidity values. Remember that the laser’s coolant temperature must be set above the dew point
temperatures given in the chart but should not exceed 22 °C (72 °F).
To use the table, look down the Air Temp column and locate an air temperature in Fahrenheit or Celsius
(°C values are shown in parentheses) that corresponds to the air temperature in the area where your
laser is operating. Follow this row across until you reach a column matching the relative humidity in your
location. The value at the intersection of the Air Temp and Relative Humidity columns is the Dew Point
temperature in °F (or °C).
The chiller’s temperature set-point must be set above the dew point temperature. For example, if the air
temperature is 85 °F (29 °C) and the relative humidity is 60%, then the dew point temperature is 70 °F
(21 °C). Adjust the chiller’s temperature set-point to 72 °F (22 °C) to prevent condensation from forming
inside the laser or RF power supply.
