All tertiary buildings, and in particular ERPs (Etablissement Recevant du
Public), are subject to standards and recommendations regarding the quality
of their indoor air. Respecting them involves regular, even constant,
monitoring of their indoor air quality. The objective of this monitoring is to
detect and report possible faults in the building's ventilation system.
This control is often done using autonomous recorders, also called
dataloggers. These measuring instruments are completely autonomous,
equipped with a large internal memory and an integrated battery power
supply. They monitor and display the air parameters of a specific area,
and can also operate in a grid to monitor the entire volume of a room to
obtain an overview of the performance of the air system.

Small, lightweight and easy to use, Sauermann's stand-alone recorders are
designed to be easily placed in any location and operate for extended periods
of time. They are accompanied by software solutions allowing measurements
recorded via USB interface or via a wireless connection to be retrieved, in order to create complete measurement reports. These devices also make it
possible to carry out a complete mapping of certain areas of the building,
which consists of checking in detail the homogeneity of the air parameters
over the entire volume of a space, and over an extended period.
