1.Working Principle of Wet Bulb Dry Bulb Thermometer
Fully wind up the spring of the Wet Bulb Dry Bulb Thermometer's ventilator and rotate the fan to provide a certain speed of air flow through two side-by-side thermometers, one of which has its mercury bulb wrapped with wet absorbent gauze.
Due to the evaporation of water on the gauze, the temperature of the thermometer drops. By comparing the temperature difference between the two thermometers (wet and not wet), the relative humidity, absolute humidity, etc. of the air can be calculated by looking up the table.
2. Main Applications of Wet Bulb Dry Bulb Thermometer
Measure the temperature and relative humidity of the air. Its structural characteristics are more suitable for measuring the temperature and relative humidity of the air in the field without power supply.

4. Composition of Wet Bulb Dry Bulb Thermometer
It consists of two identical mercury thermometers and a ventilator, with a simple structure and strong workmanship.
The Portable Weather Station with Screen (FT-PQX7) of the Seven-Element model can measure in real-time the wind speed (ranging from 0 to 70m/s), wind direction (0 to 360°), temperature (-40℃ to 80℃), humidity (0 - 100% RH), air pressure (300 - 1100hpa), illumination (0 - 157286LUX), and optical r...
The Environment Visibility Sensor is equipped with stable and efficient light sources such as lasers or LEDs. Taking the infrared LED as an example, it emits infrared light with wavelengths of 940nm, 930nm, or 870nm. After being collimated by a lens, the light is directed towards the atmospheric sam...
Visibility can be measured by visual observation, relying on manual inspection to estimate the visibility distance based on whether a certain reference object is visible. This method is simple and intuitive, but it is highly subjective and has poor standardization and objectivity.We recommend using...
In an era when the demand for meteorological information is increasing day by day, a variety of multi-functional weather stations have emerged on the market and have gradually become common devices in the field of meteorological monitoring. So here comes the question: why is it called a "multi-...
