A hygrometer is an instrument used to measure the quantity of water vapour present in air.
Hygrometers can measure relative humidity over the range of 0 to 100% RH but this range may be more limited depending on the sensor type.
Relative humidity is expressed as the ratio of the amount of water vapour present in the air or gas, to the quantity which would reach saturation, saturation being 100%.
There are a wide range of applications for % RH measurement in the following industries:
Building & Construction
Electronic Component Production
If a building is too damp and the humidity level is too high at above 70% RH, not only can Black Mould develop but such conditions can encourage dust mites to breed in carpets and mattresses.
Conversely, if the humidity level is too low at below 25%rh, it can cause respiratory discomfort.
The regular monitoring of humidity levels in buildings can improve health.
The ETI 810-130 is a Healthy Living Therma-Hygrometer with Comfort Level Indication, which simultaneously displays both humidity and temperature in addition to indicating and recording the maximum and minimum readings.
