Environmental Meters
At PCE Instruments you will find many types of environmental meters. These environmental meters are used as much indoors as they are used outdoors for measuring humidity, temperature, air velocity and air pressure. We  offer: different handheld and tabletop, environmental meters, measurement converters for industrial applications or meteorological stations. Some environmental meters can also automatically count dew point or with the ability to store data for analysis on a computer after measurements have been taken. Environmental meters are very important in industrial processes, warehouses, and of course in the private sector, such as in a house to determine interior and exterior climate and humidity in walls. For these reasons we recommend using environmental meters for testing and making the right decisions. If you don't find the environmental meters 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 98703 0 and our technical staff will advise you regarding our products.

All environmental meters are calibrated and can also be have an optional calibration done to be certified as meeting  DIN EN ISO standards. The ISO calibration consists of a laboratory calibration according to a measurement protocol and an ISO certification. Information about relative humidity: Relative humidity (r.h.) shows the relation between absolute humidity and the quantity of humidity in conditions of saturation. Relative humidity of the air is measured with environmental meters that show on their display a value from 0% (absolutely dry air) up to 100% (air totally saturated with fog, clouds or water vapour). Some models of environmental meters come with a limited measurement range. The area of physical well-being is between 40 and 65% r.h.. As hot air possesses the ability to absorb more water vapour than cold air, people feel that in wnter the air is too dry while in summer it is very stuffy. If air warms up, it increases the quantity of vapour that exsists in cases of saturation. The consequence is that the % of r.h. vapour decreases yet the real quantity of water remains constant. Something similar occurs when air is cooled, descreasing the the quantity of water vapour. In this way, the percentage of r.h. increases. Condensation forms when there is an excess of water in a saturated environment. Some of our environmental meters also offer the ability to measure relative humidity and temperature as well as the ability to calculate dew point and dew point temperature. As we have mentioned, many of our environmental meters show dew point directly on their displays.
