Nosaukums<p>This Technical Report discusses devices in photographic standardization that are used as hygrometers and</p> <p>humidistats in the measurement and control of relative humidity (RH) in test chambers and storage areas. Special</p> <p>attention is given to situations where a photographic standard specifies controlling relative humidity to _ 2 % RH or</p> <p>better.</p> <p>Electric hygrometers are recommended for their precision, low cost, and accuracy when properly calibrated.</p> <p>Calibration can be done either by the vendor or in-house by a dew-point measurement. Where the budget permits,</p> <p>dew-point combined with ambient temperature measurements (converted to relative humidity) may be the only</p> <p>sensor system.</p>
