The ETB-158 trainer is designed to experimentally demonstrate the relationship between thermal radiation and temperature, typically following Stefan-Boltzmann’s Law. It enables learners to understand how the intensity of total thermal radiation emitted by a body increases with the fourth power of its absolute temperature. This model includes a temperature-controlled heat source (usually an incandescent filament), radiation sensor, and digital meters for monitoring voltage, current, and temperature. It is ideal for physics and thermodynamics laboratories in schools, colleges, and universities. Key Features:
