SS 316 Mo is used to fabricate Combustion Bomb and its other vital parts to ensure the maximum safety of the user. Outer jacket is filled with highly insulated material so that heat transfer from / to the system is practically nil & no cooling corrections are required to get the final result.

Based on high software technology it is an upgraded version of Digital Bomb Calorimeter Model CC01/M2. Following are the additional features:

• Calorimeter vessel instead of water is filled with Highly insulated special material to avoid any temperature radiation and hence no temperature correction is required.
• Software: Digital Differential Temperature/Firing unit is provided with RS 232C Interface so that this unit can be connected with computer using software (COMPUTER at an extra cost) to get Automatic Calculation of Calorific value + other features.

•
• Function: The pressure adjusted at the pressure gauge for filling the gas remains fixed until it is changed manually or oxygen cylinder is replaced. Fix the nozzle of gas pipe on Combustion bomb and push a button on control unit. Gas will start filling the Bomb and supply will cut off automatically as soon as the adjusted pressure is achieved.

This avoid the over filling of the gas in Bomb and thereby is a key feature towards the safety of the user.

We manufacture precisely engineered single phase servo voltage stablizer which essentially has a solid state circuit to control the servo motor. The motor is mechanically attached to the arm of a continuously variable auto transformer which feeds to the primary of a series control buckboost transformer. The stablizer output voltage is compared with the reference voltage and the resultant error signal controls the Servo Motor providing true proportional control systems rather than on / off circuits.
