What exactly is a bomb calorimeter
Bomb calorimeters are used to precisely calculate the energy shift that occurs during a reaction. The original Berthelot calorimeter was developed into the contemporary Bomb calorimeter. The combined bomb calorimeter of today is constructed of corrosion-resistant steel.
An apparatus known as a bomb calorimeter is used to measure the heat of reaction at a constant volume and the measured heat, also known as the change of internal energy (E). Chemistry allows for the measurement of a reaction's heat changes at a fixed pressure or volume.
How a Bomb Calorimeter Works
The combustion heat of samples that can burn with oxygen is measured using a specific kind of constant-volume calorimeter called a bomb calorimeter. Four crucial components are
Features:
Fully automated with a coloured PLC touch-screen display
One unit; no assembly is necessary

The main functions and features :
Meter circuit design and selection of the components are according as the tolerance of greater choice of environment, so we can guarantee long-term stability of a piece of work. Basically error will not affected by the frequency, temperature, high harmonics, and the installation of location is arbitrary. After sealing unit manufactured without adjustment, greatly reduced the power sectorf+s workload of testing and calibration, meter - button box with pulse interface light coupler facilitate error testing. Detection the constant of pulse output / kw.H to find weather it is the same as constant table marked on nameplate meter, meter also provides low-frequency pulse acquisition (opts). When the one phase of three-phase three-line network is broken, three-phase four-wire network with a two-phase power outages, the watt-hour meter still normal, and display the lost pressure. Power meter in the factory before carefully debugging and test the installation of qualified lead seals. Energy applies to an ambient temperature of -25 fp c to 70 fp c and relative humidity over 85% of the region.
