Automatic Oxygen Filling

Another useful feature of the CAL3K Calorimeters


A great new feature of the CAL3K_AP. The valves for filling (inflation) and de-filling (Exhaustion) are contained inside the CAL3K_AP calorimeter and the oxygen pressure and filling rate are mentioned. This instrument is recommended in a clean laboratory environment.

This method has the advantage that the vessel pressure is monitored and controlled. In the initial phase the vessel is filled and the filling progress is monitored and appropriate messages are issued if a violation is detected.

The operator is alerted to any ‘leak’ during the initial and final phase. The pressure increase due to the vessel temperature increase is recorded and used in a result quality assessment.

The filling target pressure can be set to any pressure, but lower than the regulator pressure. The automatic filling and deflating has the following advantages:

  • Increased safety due to strict inflate procedures (e.g. any fault prevents filling)
  • Manual deflate procedure in an emergency

This feature applies to the following CAL3K Systems : CAL3K-AP.
