Product Description

The ‘Swarg Systems & Instruments’ apparatus consists of a leak tight cylinder provided with a heater, at the centre. The cylinder is evacuated with the help of the vacuum pump. When input is given to heater its heat is transmitted to cylinder wall by radiation. Cylinder wall temperature rises, which is kept steady by circulating water around it. If Stefan Boltzmann constant is assumed to be known, then heat transfer can be shown proportional fourth power of temperature or the apparatus can be used to determine the Stefan Boltzmann constant.

SPECIFICATIONS

1) Test cylinder – 200mm. dia. stainless steel cylinder provided with water circulation outside the wall with heater at the centre & thermocouples to measure wall temperature. Cylinder wall is blackened inside.
2) Dimmer to control input to heater.
3) Voltmeter & Ammeter to measure input to heater.
4) Multi channel digital temperature indicator to measure temperatures.
5) Vacuum gauge to measure the vacuum inside the cylinder.
A technical manual accompanies the unit.
The unit provided with and attractive & rust proof powder coating.
