Compliance with standards regulating controlled environments requires
multiple levels of monitoring. The air parameters must be controlled
independently of the building's air conditioning installation regulation
system, which already integrates an entire.

measurement and control instrumentation system. The objective of this
secondary monitoring is to find possible flaws in the regulation of the
ventilation system of a building, but also to quickly check the conditions of
use of certain sensitive workshops (suction host, isolation chamber , etc.).
This control is carried out 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 parameters operating in a grid to monitor
the entire volume of a room to obtain an overview of the performance of
the aeraulic 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 complete mapping of controlled
atmosphere zones, which consists of checking in detail the homogeneity of
air parameters over the entire volume of a space, and over an extended
period.
