Digital hygrometers are more precise than analog hygrometers but still
most are accurate + or – 5 points
. They are calibrated in the factory. We recommend that you check the calibration of your digital hygrometer using the salt method so that you know exactly the margin of error of your instrument.
How do I know if my hygrometer is accurate?
Dampen a towel (not dripping wet, but good and damp), then wrap the hygrometer in the towel for 30 to 45 minutes. Then unwrap it and read the humidity (quickly). If your hygrometer is perfectly calibrated (few are) it will be reading exactly 100% humidity. Most likely, it will be reading somewhere between 80 and 90%.
Is a digital hygrometer more accurate?
Digital hygrometers tend to be more accurate
and often provide additional information such as the temperature, making them more practical most purchasers. This is not to say though that a high quality, calibrated analog device cannot give you an accurate readout.
How accurate are cheap digital hygrometers?
Cheap mechanical hygrometers and cheap electronic hygrometers are supposed be
accurate within +/-7%
.
Where is the best place to put a hygrometer?
The best place to put a hygrometer is
at the top of the house and away from any windows or doors
. The reason for this is that it will give you an accurate reading on humidity levels in your home without being affected by external factors such as wind, rain, snow, or sunlight.
Do you need to calibrate a digital hygrometer?
Digital hygrometers are more precise than analog hygrometers but still most are accurate + or – 5 points. They are calibrated in the factory. We recommend that you
check the calibration of your digital hygrometer using the salt method
so that you know exactly the margin of error of your instrument.
How long does it take for a digital hygrometer to read?
To ensure that the hygrometer reads the correct humidity inside the plastic bag, leave it for
around 8 to 12 hours
. After the waiting time, check the reading on the device while it is still inside the plastic bag. If the hygrometer is accurate, it should read 75 percent.
Are digital hygrometers better than analog?
Digital hygrometers usually also have other uses, such as measuring temperature and other environmental factors in addition to the humidity level. There are some pros to using these kinds of tools, though. For instance, they are very, very accurate, and they are
often more affordable than quality analog versions
.
What should indoor humidity be?
The ideal relative humidity for health and comfort is somewhere
between 30-50% humidity
, according to the Mayo Clinic. This means that the air holds between 30-50% of the maximum amount of moisture it can contain.

Which hygrometer is most accurate?
What is the Most Accurate Hygrometer? Of all the humidity monitors we analyzed,
the Caliber 4R and Caliber IV
are the most accurate hygrometer devices. They read within ±1% RH, and the humidity range is 20-90%.
How much humidity is too much?
An indoor humidity level is too high when it’s
above 50%
. At this level, your home is susceptible to increased dust mite infestations, as well as mildew, mold growth and other bacteria. This can cause serious health issues for those who breathe in mold spores or are exposed to bacteria for long periods of time.
What is the best way to measure humidity?
The easiest way to measure your indoor humidity level is by using
a hygrometer
. A hygrometer is a device that serves as an indoor thermometer and humidity monitor.
What is an uncomfortable humidity percentage?
While there’s no set humidity threshold above which general comfort level begins to deteriorate, NOAA typically considers relative humidity (RH) levels of
50% or more
, and dewpoints (a more direct measure of humidity) above 65 F (18 C) to be uncomfortably high.
Is 60 humidity bad?
When the indoor humidity level is below 30 percent, the air is too dry, which can harm both a home’s structural integrity and the homeowners’ health. Conversely, when the level is above 60 percent,
the air is too wet, which is also harmful to both the home and the homeowners
.
What should my hygrometer read?
The hygrometer should should read
75%
. The difference is how much your hygrometer is off. For example, if your hygrometer reads 70% during the salt method test this means that to obtain the real humidity level you should add 5 points. If you have an analog hygrometer, you can correct the reading.
