E-MICRO: How to check if Internal Sensors are calibrated correctly

The integrated temperature/humidity sensors in an E-MICRO may display different readings than the external sensors connected to the system. Typically, integrated sensors display higher temperature readings and lower humidity readings, due to the conduction of the printed circuit board material. An increase in temperature without any change in the amount of water held in the air can cause relative humidity to decrease.

To see if the integrated sensor is calibrated correctly, compare the dew point of the air being read by the integrated sensor to the dew point of the air being read by the external sensor. Unlike humidity, dew point is not affected by a temperature increase. If the calculated dew point is the same for both sensors, the sensors are reading the same air and are calibrated correctly. If the calculated dew point is not approximately the same for both sensors when they are placed next to each other, contact technical support at 1-800-742-8324 (US & Canada) or 1-330-562-7070 (International).

To calculate dew point, you will need both temperature and relative humidity. Use an online dew point calculator to determine approximate dew point measurements.
