As you know, the main prerequisite for doing any work is to have proper information about that subject. In order to choose, review the prices, buy and know more about hygrometers (humidity meters), the following contents are included so that you, dear visitors of the specialized website of Damatajhiz, can use these information to choose and bulk buy all types of humidity meters from Honeywell, Satronic, Extech, Bentec, CEM, etc. brands.
Hygrometers generally measure the amount of moisture and water vapor in the air. Hygrometers measure relative, absolute, and dew point humidity. There are different hygrometers, including industrial digital hygrometers, desktop digital hygrometers, and solids hygrometers. Digital hygrometers have two types of head probes and separate probes, and solids hygrometers have two types of destructive probes and destructive dust probes. Join us in introducing and checking the performance of different types of hygrometers in the rest of this article (for wholesale purchase).
The relative humidity is used in meteorology and daily life. Relative humidity is the ratio of water vapor present in a specific volume of air at a certain temperature to the maximum weight of water vapor it can have at the same specific temperature. The relative humidity is measured in two direct and indirect ways. In the direct measurement of humidity, devices capable of directly measuring humidity are used, such as devices that are sensitive to humidity and change physical parameters such as length, width, surface, and resistance to humidity fluctuations. In measuring relative humidity indirectly by measuring two parameters, a rotating wet thermometer and a rotating dry thermometer, the amount of air humidity is measured and displayed as a graph. We can mention the Wiring hygrometer and Assman hygrometer among indirect relative hygrometers.
The amount of water vapor in a unit volume of air is called absolute humidity; its measurement unit is milligrams per liter or grams per cubic meter.
When the room temperature reaches 100% saturation with water vapor, this degree of humidity is called dew point, and it is widely used in meteorology, electronic assembly, and chemistry.
Desktop digital hygrometer: These hygrometers are desktop or wall-mounted and are used to measure the humidity of work environments, laboratories, hospitals, and generally enclosed environments. These hygrometers often cannot be calibrated.
Industrial digital hygrometers work based on whether the probe is on its own. In some models, in addition to being calibrated, it is possible to set the minimum and maximum humidity and alarms if it exceeds this limit. It is allowed.
Solids hygrometers are used to measure the humidity of plaster, concrete, soil, paper, etc. Destructive or penetration probe moisture meters of solids directly insert the pin to the extent of 5 mm in the solid, and the amount of moisture is shown as a graph on the screen. But non-destructive or non-intrusive probe moisture meters measure the humidity of solids ultrasonically and non-contact.
