Product Description
Product Overview
Standard ventilation psychrometer is designed according to the principle of ventilation psychrometer. It is equipped with two temperature sensors, one for dry bulb temperature measurement and the other for wet bulb temperature measurement. The wet bulb temperature sensor is wrapped with gauze soaked in water. The evaporation amount of the wet bulb surface of the humidity temperature sensor depends on the relative humidity of the atmosphere, and the heat required for evaporation causes a decrease in the temperature of the wet bulb. The relative humidity is calculated by the humidity formula based on the factors, such as dry bulb temperature, wet bulb temperature and atmospheric pressure at that time. The motor drives the fan to ventilate the surface of the dry and wet bulb temperature sensor, so that the surface of the sensor can maintain a substantially constant wind speed. Thus, the humidity measurement will be more stable and accurate.
