Vapour Pressure Analyser

Hallikainen Vapour Pressure Analysers have a world-wide installation base – providing operators with readouts of True Vapour Pressure (TVP) and Reid Vapour Pressure (RVP).

Our Hallikainen Vapour Pressure Analyser has a continuous output. The measuring apparatus does not have any moving parts, so there is less to go wrong. Its reliability is known and appreciated by operators around the world. For more details, see the specification below.

Our Hallikainen Vapour Pressure Analysers are manufactured in the United Kingdom and are customisable to your requirements. They are all ATEX-certified.

Why are they the choice of EPCs and Systems Integrators?

Unlike many of our competitors, our Hallikainen Vapour Pressure Analyser provides real-time, non-cyclable measurements of TVP and RVP. They use the continuous flow of the product, and because the measuring apparatus does not utilise moving parts, this reduces the cost of maintenance for the analyser.

Developed from the original Hallikainen VPA

The Hallikainen 1354 is a completely automatic Vapour Pressure Analyser for measuring the Reid Vapour Pressure (RVP – the vapour pressure exerted by a liquid at 37.8°C/100°F) for a wide range of refinery streams. Accurate measurements that correlate with ASTM D323 or D1267 can be made on samples having viscosities up to 80cP at the measurement temperature. The 1354 is unique in that the vapour pressure is directly and continuously measured in a bubble formed in an eductor jet. As such, the device has a continuous output that can be configured to read True Vapour Pressure (TVP) or Reid Vapour Pressure (RVP). The eduction method of measurement means that the analyser has no moving parts giving supreme reliability in a production environment.
