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 …
All units have a RS232 printer port. The baud speed can be set from the keyboard. 8 printout formats are available for showing different data sets on the 80 column printer. Bulk printouts are initiated from the keyboard. Printing can be exclude faulty determinations, or the can by restricted to …
APPLICABLE TO CAL3K-AP ONLY The CAL3K-AP with automatic oxygen filling monitors the vessel pressure and reports on any leak. If a leak is detected during the initial phase, then the determination is terminated. If a leak is found during the main phase, then the result is ‘flagged’ accordingly. The initial …
No Water Bucket. No Spillage. No Measuring. With the dry method, the water and container are replaced by a temperature conductive aluminium jacket which is shrunk over the stainless steel body of the vessel at a very high pressure and forms an integral part of the Vessel. The temperature sensors …
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/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 …
The high-speed operation is the result of a couple of innovations: The stainless-steel mass is less in relation to the heat sink (aluminium sleeve). A 25% reduction was achieved. The results can be predicted early in the main period due to the increased stability of the vessel temperature sensing and …
The following data retrieval methods are possible: PRINTING: 8 different keyboard selectable formats on D1 RS232 port. Initiated from the keyboard. DUMPING: Not printable output on the D1 RS232 port for capture by a PC and usable by a spreadsheet. Initiated from the keyboard. REQUEST: Data upload to a PC …
The CAL3K calorimeter range has two main compensations: Firing Wire and Cotton Compensation Sulphur Compensation Minor compensations are : Fibre Compensation (for food analysis) Moisture Compensation Gelatine Capsule Compensation A brief explanation : Cotton and firing wire Compensation : Compensates for the firing energy and the cotton thread. Entry in …
The calibration of a vessel is required before an unknown sample determination. After the calibration the data are recorded to the vessel number. The calibration data consist of the heat capacity (Bomb Factor) and other data. The Heat capacity is a measurement which describes the amount of energy (heat) needed …
The following information applies to the : CAL3K-AP , CAL3K-A Not everyone is the same and not all laboratories operate on the same guidelines. We have tried to make the CAL3K as flexible as possible and in return introduced complexity. The unit is shipped with the “DDS3K” key password installed …
