TV signal level meter is to evaluate, test the quality of radio and television signals, commonly used in measuring instruments. This paper describes the common measurement of signal level meter.
1. Measurement indicators of field strength intensity
Main measurement indicators of field intensity are: frequency range, measurement range, measurement accuracy, sensitivity, resolution and so on.
DEW point meter is used to test the DEW point of provided sample or the real environment. The dew point is the temperature below which the water vapor in a volume of humid air at a constant barometric pressure will condense into liquid water. Condensed water is called dew when it forms on a solid surface.
The dew point is a water-to-air saturation temperature. The dew point is associated with relative humidity. A high relative humidity indicates that the dew point is closer to the current air temperature. Relative humidity of 100% indicates the dew point is equal to the current temperature and that the air is maximally saturated with water. When the dew point remains constant and temperature increases, relative humidity decreases.
