This project of research study was to compare the measurement method for measure the Density of Far-Infrared on the inclined plane dimension by using standard equipment tool Net-Radiometer and the newly invented measurement meter, consisting of the round shape aluminum black color with diameter 1.56 centimeters, 2 pieces, attached with the thermocouple K type for measuring the temperature attached between the 2 sheet of aluminum. In order to measure the density of the Ray, will use Net-Radiometer and the newly invent radiometer plate, to measure the Far-Infrared from the Cylinderlic Far-Infrared generator, at the same spot, the Voltage value that obtained from Net-radiometer, the temperature of the ray receiver plate, and the temperature of the environment from the thermocouple will be taken to calculate the density of the Far-Infrared using the theory for comparison.
The result from this study project found that the density of the Far-Infrared that measure from the Net-Radiometer have the value , which consistence with the reverse Square -root law. Fro the result of the density of the Far-Infrared that measure from the thermocouple have the value , consistent with the revers Square -root law. Beside also found that the relationship between the density of the Far-Infrared and the differentiation of the temperature that obtained from the receiving plate and the temperature from the environment were consistence with the polynomial equation, and have the value and when compare with the density of the Ray which measured by the Net-Radiometer and the Thermocouple plate at the same spot on any incline plane that parallel Cylinderlic Far-Infrared generator found the result were in consistence in the same direction.
