Calibration facility for the low dew-point temperature range

Project Description

A new dew-point generator is to be built at SP. With the new generator, the low limit and uncertainty of the realized dew-point temperature scale will be lower than with the old generator. The goal is to reach a dew-point temperature of at least –50 °C. The knowledge and experience gained at MIKES with low range facilities will be transferred to SP on a consultant basis. The project will end with a comparison between the calibration facilities at SP and MIKES.

Final Report 2009-03-16

A new dew-point generator is developed at SP. With the new generator, the low limit and uncertainty of the realized dew-point temperature scale will be lower than with the old generator. The goal is to reach a dew-point temperature of at least –50 °C. The knowledge and experience gained at MIKES with low range facilities will be transferred to SP on a consultant basis. The project will end with a comparison between the calibration facilities at SP and MIKES.

The generator was developed and tested. The comparison between SP and MIKES was not arranged.

Progress Report 2005-03-15

A new dew-point generator is developed at SP. With the new generator, the low limit and uncertainty of the realized dew-point temperature scale will be lower than with the old generator. The goal is to reach a dew-point temperature of at least –50 °C. The knowledge and experience gained at MIKES with low range facilities will be transferred to SP on a consultant basis. The project will end with a comparison between the calibration facilities at SP and MIKES.

In 2004, the generator was developed further and tested. The characteristics of the apparatus will be studied further with the MIKES dew-point comparator in 2005.
