EFERENCES Verified by
NM i, the Dutch calibration organisation, and traceable to Dutch and international standards.S
YSTEM Precision bore glass tubes with mercury sealed piston; automatic temperature and pressure compensation.G
ASES Each instrument is calibrated under the actual operating conditons whenever possible. A number of standard gases is available.F
LUID D
ATA Wehave accumulated a data bank (F
LUIDAT ) that enables us to accurately determine the gas properties , such as density, specific heat and viscosity under the prevailing operating conditions . These are necessary to accurately calculate the (sliding) conversion factor by means of the F
LUIDAT program, which is integrated in our calibration program.
