Hydromette BL Compact TF 3
4 Application instructions
On the following pages, you will find information on the various
measuring modes of the BL Compact TF 3 (Chapters 4.1, 4.2 and
4.3) and on the operation of the device.
4.1
Measuring air humidity
4.1.1
Absolute humidity
The amount of water vapour in g/m³ in the air is termed absolute
humidity. The amount of water vapour cannot exceed a fixed
specified amount.
𝐻𝑢𝑚𝑖𝑑𝑖𝑡𝑦 (𝑎𝑏𝑠𝑜𝑙𝑢𝑡𝑒) =
𝑚𝑎𝑠𝑠 𝑜𝑓 𝑤𝑎𝑡𝑒𝑟 (𝑔)
𝑣𝑜𝑙𝑢𝑚𝑒 𝑜𝑓 𝑎𝑖𝑟 (𝑚

)
4.1.2
Moisture saturation
Moisture saturation is the maximum amount of water that can be
contained in a certain volume of air. The higher temperature the
larger the amount of water that can be held in the air.
𝐻𝑢𝑚𝑖𝑑𝑖𝑡𝑦 (𝑠𝑎𝑡𝑢𝑟𝑎𝑡𝑖𝑜𝑛) =
𝑚𝑎𝑥𝑖𝑚𝑢𝑚 𝑚𝑎𝑠𝑠 𝑜𝑓 𝑤𝑎𝑡𝑒𝑟 (𝑔)
𝑣𝑜𝑙𝑢𝑚𝑒 𝑜𝑓 𝑎𝑖𝑟 (𝑚
