Calibrating your Humidity Gauge | The Crab Street Journal

Feb 21, 2013 · Put the shot-glass and hygrometer in a wide-mouth jar, and seal it airtight. After six hours (or more), the humidity in the jar is 75%. The hygrometer should read somewhere around 75%. If it does not, take the screwdriver and turn the screw on the back of the hygrometer until the meter reads 75%.Get price

How do I calibrate my hygrometer? (Humidity Gauge)

Although humidity gauge is pre-set at the factory, its calibration may be off within this range for various reasons. A simple, easy to do at home means of calibrating hygrometers uses standard salt and a sealed container. Table salt, when used properly, will maintain an exact 75% humidity in a perfectly sealed environment.Get price

Humidity Calibration | Generators Calibrators | Fluke

Performing a thorough calibration is important. You can perform a spot-check or one-point probe calibration in the field with a handheld humidity meter, but its value is limited. Calibration with a handheld meter needs to be carefully managed. Temperature differences between the probe and its environment, technician body heat, and even moisture from breath can all cause RH measurement errors. Furthermore, one-point tests can cause out-of-tolerance readings when ambient conditions change.Get price
