Product Specification Sheet
Stefan's Constant Apparatus (Electrical)
Model Number: MT-E092E
The Stefan's Constant Apparatus (Electrical) is a precision laboratory instrument designed for determining Stefan–Boltzmann Constant and studying the electrical characteristics of a filament lamp. Manufactured by Micro Technologies, it combines digital measurement, regulated power supply, and variable voltage control for accurate laboratory experiments.
Product Specification
The Stefan's Constant Apparatus (Electrical) is a laboratory instrument developed for studying Stefan–Boltzmann Law through the electrical heating method and determining the resistance variation of a filament lamp at different voltages. Manufactured by Micro Technologies, the apparatus enables students to understand the relationship between electrical energy, filament temperature, and thermal radiation.
Designed for engineering colleges, universities, polytechnic institutes, and research laboratories, the apparatus provides a complete experimental setup for measuring cold filament resistance, plotting current-voltage characteristics, and calculating Stefan's Constant using electrical measurements.
The system incorporates a regulated 0–300V DC, 2A power supply for supplying controlled voltage to the experimental lamp. Built-in digital voltmeter and digital ammeter provide precise monitoring of voltage and current during experimentation.
A 230V, 100W filament lamp serves as the experimental element. The applied voltage is smoothly varied using a 2A Variac, enabling resistance measurements from low voltage up to the rated operating voltage. Students can determine the cold resistance of the filament, calculate resistance at various temperatures, and plot voltage-current graphs for detailed analysis.
The trainer is manufactured using a high-quality insulated printed circuit board with clearly printed circuit symbols and is protected by an MCB for safe operation. All experimental connections are provided through a 2-pin DIN connector, while the complete unit is housed in a rugged metal cabinet for reliable long-term laboratory performance.
