Humidity testers
On our website, you will find humidity testers that can measure relative air humidity, or combined devices that can also  measure temperature. These humidity testers measure different ranges of humidity depending on the model. Such devices that measure air and other parameters from your surrounding become more and more important in daily life. Relative air humidity is an important factor in most sectors, including industry, transport and gardening. In today's world they are especially very helpful in offices where the working atmosphere needs to be perfect in order to ensure best working conditions for everyone. Another important branch are the private households. If the humidity is too high in a private household, mould might occur on the walls or on the roof. This means a health risk for everyone who lives in that environment. Humidity testers are versatile in that they can take measurements, store them to memory and transfer data to a computer for further detailed analysis. There is also the calibration standards for the device which makes it easy to ensure that measurements are extremely accurate. Many of our humidity testers come with an ISO calibration certificate and some models are legally validated. They are very useful in evaluating damage in a warehouse. If you can't find the humidity testers 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: +44 (0)2380 987030 and our technical staff will advise you regarding our products.

All humidity testers 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 that 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 humidity testers).

Information about relative humidity: Relative humidity (r.h.) shows the relationship between absolute humidity (the amount really there) and the saturation state of water vapours. Relative air humidity is measured using humidity testers, that show on their displays from 0% (absolutely dry air) up to 100% (air that is completely saturated, such as fog, clouds or steam bath). Some models of humidity testers 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. Some of our humidity testers offer the ability to not only measure relative humidity and temperature, but can also 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 independant of the actual temperature. One possibility of 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 humidity testers show dew point on their display.
