Bomb Calorimeter for Measuring of Calorific Values of Combus
ACCURATE TEST RESULT:
The data is real and reliable.
After the starting, the first time experimental data is accurate, does not have the experimental result to become invalid at the first time test, the continual operating time reaches 72h;
All data is actual, real and objective does not use the software to adjust or change test result, to piece together the data.
REASONABLE STRUCTURE, SECURITY AND ENVIRONMENTAL PROTECTION:
The system structure layout is reasonable, no complex oxygen bomb elevating mechanism, avoids the mechanical breakdown, the instrument runs stably.
Does not use the compressor refrigeration, the instrumentation sound is lower than 40 decibels, does not have the noise pollution.
With self-diagnostic function, accurately judge and prompt various functional unit is whether working normal during the test procedure, easy to maintain, guarantees the system normal operation.
The watch-dog and machinery protective device provides full protection, prevents the instrument abnormal.
HIGH AUTOMATION AND HIGH EFFICIENCY:
Automatic water temperature adjustment and water weighing as well as automatic measuring of total water volume.
External balance weighing connected to the calorimeter, automatic send and save and pronounce by voice the sample weight, the operation is simple and reliable.
The jacket water and the testing water is separated and the jacket water temperature is always higher than the bucket water temperature and the difference is relatively constant, thus to isolate the influence of the environment to the bucket.
Easier operation and convenient maintenance; Double-head oxygen bomb. Firing wire is tied by Sleeve-Pressure Methodwhich is convenient, safe and reliable.
Automatic identification of the heat capacity corresponding to 100 oxygen bombs.
EASY OPERATION:
Light and aesthetic.
The instrument is controlled by only one switch.
It prompts in English characters in the complete process, test completion just by prompt-based operations.
Software featuring good error tolerance. No worry about wrong operations.
Convenient calculation and printing of gross/net calorific values.
Capable of multi-control and will not be interfered by each other. Automatically identify the parallel samples and calculate the average and error value. Capable of multi-copy printing.
Rich inquiry functions, supportive to ambiguous inquiry.
