In this way, our MGP-1 Standard Gas Mixer, designed to facilitate the calibration of gas analyzers, verifying their linearity at various points from a single standard gas bottle and an inert gas bottle that acts as a diluent has Been approved by CEMIC. Thus the center, as a department of the University of Barcelona has carried out a detailed study of the benefits of the MGP1, issuing a very favorable report and granting the homologation thereof. A team based on the innovative method called “binary flow combination”. Uses 4 mass flow meters controlling-measuring at a single flow rate, always 100%. Guaranteeing a precision of 4 to 5 times better when avoiding the use of the meter of flow in the bottom of its range.
