How do I determine the exact flashpoint of my oil?

It is important to know that light-ends are volatile and therefore, taking an open, hot sample of heat transfer oil provides a wrong result. Then, the sample shows a too high flashpoint and with this, a too positive result, although the flashpoint is possibly lower.

For the analysis it is most important to receive a representative and exact sample. This is ensured by a closed, cooled sampling technology.
In the NESS Sample Cooler (NPK40) the sample is cooled down by water to a temperature, at which light-ends cannot evaporate from the sample anymore. This ensures a representative analysis result.
