For your calibration of static pressure measurement instruments, LNE possesses references extending from the ultra-vacuum all the way to the highest pressures (10,000 bar), with uncertainty among the very best levels. The calibration chain and methods deployed are synchronized with the International System of Units (SI) for nearly the entire line of pressure instruments.
Depending on the desired level of uncertainty, calibration by pressure equivalence or by determination of the efficient cross-section and strain coefficient.
Any type of manometer or pressure sensor with uncertainties extending to 5.10-5 of the measurement range.
Range of absolute pressures from 10-6 Pa to 15 kPa:
Determination of the leak due to pressure variation or by means of comparison with a standard reference leak.
Range covered from 10-10 Pa.m3.s-1 to 10-2 Pa.m3.s-1
List of sites and scopes available on www.cofrac.fr
Calibration operations by means of direct comparison with national references are possible for connections at the highest metrological level.
Calibration at temperatures other than 20°C.
Adjustment and modeling of calibration results plus metrological verification are additional services performed upon special request.
A technical accompaniment service may be tailored to suit your specific needs.
