Description and Specification for Lab Tenders
Astra Scientific Bomb Calorimeter.
A Bomb Calorimeter measures the amount of heat generated when matter is
burnt in a sealed chamber in an atmosphere of pure Oxygen gas.
Bomb Calorimeter provides a simple inexpensive yet accurate method to
determine the Heat of Combustion, Calorific Value and the Sulphur
contents of solids & liquids and fuels. The outfit provided is
complete for the analysis as per methods recommended by the Indian
Standard Institute (IS: 1359 –1959), British Standard Institute (BS
1016: Part 5:1967) and the Institute of Petroleum (IP 12/63T). Each part
of the outfit has been finished and tested according to the
specifications laid down by these Institutions.
