Precautions for the use of hygrometers What is a hygrometer? In fact, this kind of instrument is used to determine the temperature and humidity of the environment to determine the environmental conditions of production or storage. It also applies to people's daily life. The application is more extensive. When there is a lot of moisture in the air, we say that the air is moist.
The thermometer and hygrometer are generally divided into two types: pointer thermometer and hygrometer and digital thermometer and hygrometer. The pointer is cheap and is only suitable for home use. The digital thermometer is not the same as it has high precision and can be seen directly at a glance. Indoor temperature and humidity. So the figures are still more like people.
Precautions and measurement range for use of hygrometer:
Just like the measurement of weight and temperature, selecting the humidity sensor first determines the measurement range. In addition to the meteorological and scientific research departments, the measurement of temperature and humidity generally does not require full wet-range (0-100% RH) measurements. The accuracy of the measurement is the most important indicator of the humidity sensor. Every æ高-percent increase in the humidity sensor is the last step or even the last step. Because to achieve different accuracy, the manufacturing costs vary greatly, and the price difference is very far. Therefore, users must tailor their clothing to avoid blindly pursuing "high, fine, sharp".
Digital Humidity Meter Applications:
Humidity sensors have been widely used in industry, agriculture, meteorology, medical care, and daily life. In particular, with the development of science and technology, more attention has been paid to the detection and control of humidity and much research has been done. jobs. In general, the characteristics of an ideal humidity sensor are suitable for use in a wide range of temperature and humidity, with high measurement accuracy, long service life, good stability, fast response, low hysteresis, and reproducibility. Good; high sensitivity, good line shape, small temperature coefficient; simple manufacturing process, easy mass production, simple conversion circuit, low cost; corrosion resistance, low temperature resistance and high temperature resistance.
