S.T.A. Branca Idealair: Mission

Since 1932 until today ...


BRANCA IDEALAIR S.a.s. initiates design and development of textile testing instruments.

The symbol of our company is its first apparel called REGAIN TESTER.

The device consists of a rapid drying oven equipped with an analytical balance. After drying the fiber material with a known wet mass, the regain tester determines the final dry weight by comparing the mass differences between two successive drying operations. If the mass difference is equal to or less than the allowable difference in grams, the moisture content and recovery of the fiber material is determined.

Relative humidity (%) is an important factor influencing fibers, and the need to control it is becoming so fundamental for textile testing laboratories that it is a keyword to ensure the validity of trade weights of materials in national and international textile markets.


Then the experience brings to the birth of a new base concept: "The STANDARD ATMOSPHERE".

Branca Idealair is specialized in the realization of precision air conditioners that have a great success and guarantee the thermohygrometric stability required in laboratories, offering the best quality in all their projects.

In the early 1970s, with the advent of quality management systems, the requirements for climate units capable of controlling laboratory parameters that determine higher quality products and control processes were increased.

The more and more recommended requirements for the geometry of the pieces in terms of dimensional metrology show that they are affected by temperature variations: the reference standard ISO 1 defines as reference temperature the 20 C for the geometrical specifications.

Metrology laboratories where such specifications are recommended must maintain very tight tolerances on variables to minimize thermal gradients that cause spatial and temporal variations that are unacceptable, especially for coordinate geometry in dimensional metrology (CMM).


For many years, Branca Idealair has continued to develop new special and custom products based on the specific requirements of customers for the quality of their industrial products.

Our new range of air conditioning units include advanced technology assuring a precise close control of temperature, for example at 18-24C 0,5C or 0,1C and Relative Humidity at 50-65 % 2%, thus creating the right conditions to perform repeatable tests in compliance with national and international Standards.



Branca Idealair is proud and happy to promote its know-how by offering the entire realization of QC laboratories that allow to apply the calibration of laboratory equipment and test instruments to reduce to a minimum the thermal contribution to the measurement uncertainty.
