Variable Filling Pressure | CAL3K Features

The oxygen filling pressure is pre-regulated to 30 bar at the oxygen bottle. This is the standard filling pressure for bomb calorimetry. If needed and for special samples such as powders or wood samples a lower filling pressure can be used with good results. It is also possible to save oxygen for the determination of routine samples. In all these instances, the vessel filling pressure can be set lower from the keyboard.

The default setting is 30bar.


The parameters associated with the filling pressure are:

Recommended Minimum filling Default 30bar
Minimum filling Default 20bar

START A CALIBRATION

The calibration of the CAL3K is a process in which a substance (Benzoic Acid, BA) of known calorific value is burned so that future burning of unknown substances can be compared to it. In other words the calibration records all the system variables such as temperature rise and heat loss in memory. All this data is called a calibration field. The calibrations are stored in the vessel.

PERFORMING A CALIBRATION

To perform a standard calibration using Benzoic Acid Tablets you will need : A working oxygen bomb calorimeter system connected to a power source, A CAL3K Manual Oxygen Filing Station connected to an oxygen supply (not needed when using the CAL3K-AP Calorimeter)...

INTELCAL SYSTEM CALIBRATION

The CAL3K system uses two calibrations: Keyboard calibration, in real time, one sample, average with last ‘n’ calibrations, PC calibration, in retrospect, multiple samples. The PC calibration is called ‘IntelCal’ because of its complexity and system effectiveness.
