Low Power Consumption | CAL3K Features

The average power consumption is about 0.6 watt.

However, just after firing the power consumption increases to 24 watts for 3 minutes in the CAL3K-A / CAL3K-AP.

Other units without the ATC (Automatic Temperature Control - Heater) require not more than 1.2 watt.

This means that the CAL3K does not contribute significantly to heating the environment.

It can operate from a 12V battery for prolonged time.


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.

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)...

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.
