A hygrothermograph is a device that is used to simultaneously record temperature and humidity on a line chart. It’s also a hygrometer thermometer barometer. It might be either battery-powered or spring-wound. The device records data, in the form of a line, on a roll of paper that is mounted on a revolving drum, which turns at a predetermined rate. This system provides a visual representation of fluctuations in temperature and humidity over a given time period. Lines on the chart are drawn by two separate pens, one attached to a temperature-sensing element and the other attached to a humidity-sensing element.

Recently our company launched a new mini hygrometer thermometer barometer. It was designed for household. It’s length is 0.08 meter, width is 0.021meter, height is 0.061 meter, which is very small and portable. Magnet on the back let it can be adsorbed on the refrigerator or anything contain iron. The bracket can help stand easily. This mini hygrometer thermometer barometer measures the real-time temperature and humidity, record 24 hour max/min temperature and humidity. And the temperature can display on degree Celsius or degree Fahrenheit. With this digital hygrometer&thermometer, you can know the production or warehouse environmental conditions very convenient. On the screen the upward tilted arrow means real time temperature is higher than the last updated temperature. Straight arrow means real time temperature is the same as the last updated temperature. Downward tilted arrow means real time temperature is lower than the last updated temperature. You can know the temperature changes more directly.

Sudden changes in temperature and humidity can cause discomfort to the human body and even cause illness. Therefore, you need to buy a home thermometer and hygrometer to monitor the changes in temperature and humidity at any time to give you a health protection.
