Do you know about manual temperature and humidity meter

Temperature and humidity meter which has been widely applied to determine the temperature and humidity environment, in order to determine product production or storage environment conditions. Also used in People's Daily life. Wet and dry bulb method, this is the 18th century was invented by wet method. With a long history, the most commonly used. Dry wet ball method is an indirect method, which use wet and dry bulb equation conversion humidity value, and this equation is conditional, namely wind speed near the wet bulb must reach 2. More than 5 m/s. Common use of dry wet bulb this condition is simplified, so its accuracy is only 5 ~ 7% RH, wet and dry bulb does not belong to the static method, don't simply think that as long as to improving the measuring accuracy of two thermometer is to improve the measurement precision hygrometer. Meter below introduce you to a commonly used hand-operated dry wet thermometer: WD - 6 a temperature and humidity meter, the product name: dry and wet thermometer, hand-operated dry wet thermometer use areas: family, hospital, hotel, office, meteorology, scientific research departments such as three, specification description: models: WD - Six types: temperature and humidity meter structure: manual material: yellow ABS shell body, the blue handle shape dimension: yellow 220 * 45 mm blue handle 84 mm long temperature range: 0 - 50摄氏度 0 - 100% RH: precision & plusmn; 1 c four, product features: the temperature and humidity meter display temperature, intuitive and convenient; Safe and reliable, long life, fast reading.
