Branca Idealair s.a.s. starts studying the development and improvement of innovative testing instruments for Textile; the symbol of the company is its first realization, the Regain tester 70, which is based on a drying chamber equipped with a balance; after placing the fiber materials of pre-determined weight inside the chamber, the oven dries it until the difference between two successive weights is equal or lower than the maximum difference in grams admitted according to the conventional regain values of textile materials.
The Relative humidity (%) is then recognized as an important influence on fiber testing and the need to control it becomes so fundamental for textile laboratories that represents a key point to ensure the validity of commercial weights of materials in the trade market.
Then the experience brings to the birth of a new base concept: "The STANDARD ATMOSPHERE".
Branca Idealair becomes skilled in the realization of precision air conditioning systems that can guarantee the thermo-hygrometric stability required inside the laboratories offering the best quality in all its projects.
The Requirements ever more recommended on the geometry of the pieces in terms Dimensional Metrology demonstrate that they are influenced from Temperature variations: the reference Standard ISO 1 defines as reference temperature the 20 °C for the geometrical specifications.
The laboratories for Metrology, where such specifications are recommended, have to maintain very closed variables tolerances to minimize thermal gradients, which determine spatial and temporal variations unacceptable especially for the coordinate geometry in Dimensional Metrology (CMM).
For years and years Branca Idealair continues developing new special and custom systems always based on the specific requirements expressed by the Customer and on the application fields.
With a fine control adjustment of Temperature, for example at 20°C ± 0.5°C or ± 0.1°C and Relative Humidity at 50 ± 2%, thus creating the right conditions to perform repeatable tests in compliance with national and international Standards.
> Today, Branca Idealair is proud and glad to promote its know-how offering the entire realization of QC Laboratories that allows to apply the calibration of lab equipments and testing devices in order to reduce at the minimum the thermal contribution to the uncertainty of measurements.
