Relative Humidity Meters

On our web page, you will find several devices to measure relative air humidity, or combined devices to measure both, temperature and relative humidity. Each relative humidity meter measures different ranges of humidity, depending on the type of instrument. Relative air humidity is an important factor in a lot of sectors including industry, transport or gardening. Relative humidity meters are versatile instruments that perform measurements, store values in an internal memory and are also capable of transferring data to a computer for further analysis. The calibration standard for relative humidity meters makes it easy to ensure that measurements are accurate. Many of our relative humidity meters come with an ISO calibration certificate and some models are legally validated. They are very useful in evaluating humidity values in warehouses, office buildings or certain industrial-spaces where certain moisture levels have to be met according to specifications or due to product properties. If you can't find the relative humidity meter you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our offices on: UK customers +44(0) 23 809 870 30 / US customers (561) 320-9162 and our technical staff will advise you regarding our measuring instruments.

All relative humidity meters come calibrated, but as their sensor's accuracy deteriorates with use they should be recalibrated on a regular basis. A calibration can be done by the user of the device by using the optional calibration standards or the device can be sent to us and we will perform a recalibration that will meet ISO standards. (Calibration / recalibration of relative humidity meters).

Information about relative humidity: Relative humidity (r.h.) shows the relationship between absolute moisture (the amount really there) and the saturation state of water vapours. A relative humidity meter measures the relative humidity and shows the corresponding value on a display between 0% (absolutely dry air) and 100% (air that is completely saturated, such as fog, clouds or steam baths). Some models of relative humidity meters have an unlimited measurement range. The physical area is between 40 and 65% r.h. Given that, hot air possesses the ability to absorb more water vapour than cold air, people feel that in winter, air is too dry and in summer it is too humid. If air heats up it increases the amount of water vapour to that of saturation. The consequence is that the % of relative humidity decreases while the real quantity of water remains constant. Something similar occurs when air is cooled, decreasing the quantity of water vapour. This increases the percentage value of relative humidity. Condensation forms when there is an excess of water in saturated conditions. Due to this, the temperature of the air where the relative humidity is measured is a very important factor in order to classify the determined values. Because of this, we offer relative humidity meters with the ability to not only measure relative humidity and temperature, but also to calculate dew point and dew point temperature. Dew point temperature is defined as the temperature at which the actual vapour content of air is the maximum (100% relative humidity). Dew point temperature is independent of the actual temperature. One possibility to find out the dew point temperature is freezing metal until its surface forms condensation. The temperature of the metal will then be the dew point temperature. As we have mentioned, many of our relative humidity meters show dew point on their display.
