Humidity indicators
On our website, you will find humidity indicators that can measure relative air humidity, or combined devices that can also measure temperature. These humidity indicators measure different ranges of humidity depending on the model. Relative air humidity is an important factor in most sectors, including industry, transport and gardening. They 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 indicators 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 indicators 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 products.

All humidity indicators 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 indicators).

                                                        
     Recalibration standards                         Some devices use a                    ISO calibration certificate
    for humidity indicators                        calibration chamber                      for humidity indicators
 

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 indicators, 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 indicators 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 indicators 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 indicators show dew point on their display.
