The following is an excerpt, download the complete article here.
The importance of temperature Relative humidity is extremely temperature dependent. For the best possible calibration results, all apparatus used for calibration should be in temperature equilibrium. This means that the calibration environment should be at a stable temperature, and that the working standard and unit under test must be at the same temperature. If these conditions are not achieved, the calibration will have error caused by temperature gradient. In practice, this means that portable working standards must be given time to equilibrate when used in the field. This is particularly true when a standard that has been stored at room temperature is used in a process or environment that is warmer or cooler than room temperature.
The article further discusses these calibration methods:
- One point in-situ calibration
- Multi point field calibration
- In-house laboratory calibration
- Using an outside commercial calibration lab
