In a room, temperature and RH levels may vary dramatically from location to location. Such
factors as air stratification, drafts, and proximity to heat or humidity sources (people,
equipment, moisture, solar gain, etc.) can contribute to a wide variance in conditions even
within a small, confined area. The individual sensors associated with your SmartReader 2
measure and record temperature and RH only in one location. They do not, in any way,
represent an overall reading.
If you decide to check the calibration of your SmartReader 2 RH Module using a Sling
Psychrometer, keep in mind the following:
· Any instrument that requires a person to be present at, or in very close proximity to the
RH sensor in order to get a reading, will have a measurement error introduced to it.
That is because the body readily gives off heat and moisture that is especially
noticeable at lower RH levels.
· The time taken between slinging the psychrometer and reading it can exhibit several
degrees of inaccuracy in the wet bulb reading. Air currents around the body, whether it
is slung in the shade of a building or in sunlight, not knowing how to tie the wet sock, its
condition, and the purity of water used, all contribute to error. In addition, interpolating
the data from a psychrometric chart can add another 2 to 4% to the accumulative error.
1.4.5 Relative Humidity Calibration
Each relative humidity sensor has been individually calibrated in an environmental chamber
with standards traceable to the National Institute of Standards and Technology (NIST).
The SmartReader 2 and the EH-020A probe are supplied with a calibration certificate which
provides calibration values. These calibration values must be entered in and stored in the
logger during initial setup. If your RH sensor is out of calibration, you can simply replace it with
a new one.
NOTE: A straight replacement of the RH sensor will introduce an additional +2%
tolerance on the RH accuracy. Calibration of the RH channel with the new RH
sensor is recommended.
In the event that you wish to confirm the RH calibration of your sensor, you can perform your
own field test. Refer to Appendix B Temperature and Relative Humidity Calibrations for more
information on RH testing.
Interchangeable replacement RH sensors for loggers are available through your dealer. For
best accuracy, it is recommended these be calibrated together with the logger - consult your
ACR representative for price and availability of this service. Replacement EH-020A modules
which are pre-calibrated are available through your dealer.
