Fast, Accurate, and Versatile Operation

This semi-automatic bomb calorimeter delivers quick results with immediate response upon combustion. It accommodates standard samples (0.5-1 g) for single test runs, ensuring efficiency while maintaining high accuracy (0.1% of reading) for a wide measurement range (0-8000 cal/g).

FAQ's of Bomb Calorimeter (Fssai):

Q: How does the bomb calorimeter determine the calorific value of food samples?

A: The bomb calorimeter measures energy by combusting a known amount of solid or liquid food sample within its stainless steel pressure vessel. The heat released raises the temperature of water in the surrounding jacket, which is measured and used-along with calibration data-to calculate the sample's calorific value.

Q: What calibration method is used for accuracy in this calorimeter?

A: Calibration is performed with the benzoic acid tablet method, a standard procedure that ensures the unit provides highly accurate and reliable measurements in line with FSSAI/ISI/ASTM requirements.

Q: When should I use the pressure release valve on the bomb calorimeter?

A: The pressure release valve is a key safety feature and should be used after the combustion process is complete and before opening the bomb vessel, ensuring safe dissipation of any residual pressure inside.

Q: Where can this bomb calorimeter be operated?

A: This bomb calorimeter is designed for laboratory use and is suitable for environments with ambient temperatures between 10C and 40C and humidity levels up to 85% RH. Its benchtop design ensures easy integration into standard laboratory setups.

Q: What is the process for filling the bomb with oxygen before testing?

A: Before starting a test, the supplied manual pressurizer pump is used to fill the bomb vessel with oxygen at up to 30 atm, which is essential for complete combustion of the sample during calorimetric analysis.

Q: How do I benefit from using this semi-automatic calorimeter?

A: Users benefit from fast analysis (immediate response upon combustion), high measurement accuracy (0.1%), ease of operation, and robust safety features. It is ideal for routine calorific testing in food analysis laboratories, facilitating compliance with FSSAI standards.
