Read Vessel Pressure

The following information applies to the : CAL3K-AP

The ‘READ’ Keyboard commands are ‘non-influential’, they just monitor in real time a particular condition.

To activate the reading of the vessel Pressure type:

The Vessel pressure is available and updated regular during the initial and main period. Check how the pressure is increasing during firing. To get out of the ‘dynamic’ display type ESC.

A much better pressure graphical presentation is available on the PC screen!


Our top of the range product is our faster calorimeter in the CAL3K range. The CAL3K-AP has a sample repeat speed of 4-6 minutes per sample and can handle more than 10 samples per hour for faster throughput. The CAL3K-AP is suited for a clean and well maintained laboratory with a requirement for very fast and accurate results.

The traditional CAL2K-4 bomb vessel has been replaced with a self-locking and sealing bayonet vessel with built-in temperature sensors. The vessel is completely removable for easy sample management, cooling, cleaning and maintenance. The CAL3K bayonet (self-locking and sealing) vessel has a stainless steel body with a reduced mass (approx. 1.9kg) and a pressed on aluminium sleeve which acts as a heat sink and temperature equalizer. This sleeve performs the task of the traditional water and stirrer.

The pressure transducer which monitors the vessel pressure for Filling and oxygen leakage needs to be offset adjusted so that it reads ZERO at atmospheric pressure. Although a pressure offset of 0.2 bar makes no difference to the CV determination, it can cause concern during the safety precautions and the power up check.
