Abstract

The results of a comparison in differential pressure between CEM-Spain and CENAM-Mexico are presented here. The comparison was performed in 2008. A high accuracy digital manometer was used for the comparison. The manometer had good behaviour during the period of the comparison, having a small drift which had no effect in the comparison. The results of the measurements showed very good agreement between the measurements performed by CEM and CENAM. For the range of the comparison it can be said that CEM and CENAM have equivalence of measurements.
