Measurements
-
Temperature – °C/°F
-
Humidity - %RH (Relative Humidity)
Sampling Methods
•
Account for the time of day (morning, afternoon, evening etc.)
•
Account for the surrounding area (5m away from area, 10m away from area, etc.) to determine
if there are significant changes in the reading
•
Consider the time of reading if taken during shift work, sometimes shift work is slow at the
beginning and slows down as shift comes to an end
•
Determine if outside weather affects the reading (open or close area)
