Energy in nature - model for comparison of solar heat absorption, analog set with power supply

Energy in Nature - is a series of models for school experiments with heat absorption. The kit includes a radiation comparator apparatus showing during simple but showy experiments how energy of the Sun is absorbed in nature.

The heat absorption radiation comparator, with heat source and differently coated domes attached, is ideal for comparing the heat absorption and radiation between shiny and dull items. The thermometer holders on each dome make it easy to use and obtain measurements. The experiment guide included is a great aid for learning about how to use the apparatus and is very user-friendly.

Kit includes:
Model for comparing solar absorption (radiation comparator apparatus), white screen, electric bulb (heat source), non-mercury thermometers (2 pcs.), power supply, cables (set).

Specification of the elements:
