What is a hygrometer? How many types are there? What to do?

Monitoring the temperature and humidity indoors – outdoors is very important, because it affects people’s health. To do this well, the hygrometer will be an effective assistant to help us monitor and adjust the temperature and humidity to the appropriate level. Let’s find out with lassho.edu.vn what humidity is, as well as the types of hygrometers and the functions of this device!

What is a hygrometer?

Thermohygrometer is a device used to measure the parameters of temperature and humidity in the surrounding environment. When the temperature or humidity readings in the room exceed the allowable threshold, the device will warn us to adjust back to the appropriate level . Helps to detect changes in temperature in the room in time and to ensure health and avoid machine damage .

Structure

Humidity thermometer has a simple structure, including 2 main parts :

• The outdoor wireless transceiver is used to determine the outdoor humidity and temperature.
• LCD display for measuring indoor temperature and humidity. In addition, this unit also displays the humidity and outdoor temperature transmitted by the transceiver.

Working principle

This type of hygrometer works based on modern technology digital sensor, so the sensitivity is extremely high and accurate. The thermal sensor is capable of recording changes in temperature and humidity from the surrounding environment even at the smallest changes. Then that data is transmitted to the receiver, which is an indoor LCD screen that displays all parameters in percentage form.

What is a hygrometer used for?

Families often use a hygrometer to monitor the temperature and humidity in the house, thereby making appropriate adjustments for the air conditioner, dehumidifier, humidifier, etc. to improve the air quality in the room. , helping to maintain health and preserve personal property.

In addition, the hygrometer is also used in places: hotels, restaurants, hospitals, offices, factories, …. to protect human health when working at that place.

Types of thermometers and hygrometers

Mechanical hygrometer

As a type of temperature and humidity measuring device using a spring, depending on the temperature and humidity, the spring will expand or contract, thereby indicating the humidity value.

Electronic thermometer hygrometer

This type of hygrometer uses an electrical sensor instead of a spring like a mechanical hygrometer. The resistance of this sensor is affected by humidity, thereby displaying the humidity value at the current time.

Compare the advantages and disadvantages of mechanical thermometers and electronic thermometers:

	Mechanical hygrometer	Electronic thermometer hygrometer
Accuracy	Good mechanical hygrometer has very high accuracy.	Has high accuracy, but less reliable than mechanical thermometer.
How to read the index	The user must manually read the index on the scale.	Display the temperature value with humidity on the LCD screen.
Design	Simple design, less eye-catching.	Sophisticated, modern design.
Mechanism of action	Use spring contraction.	Use the power sensor from the battery’s power source.
Other utilities	Do not have	Integrating many other features such as: Display time, date, month, measure air pressure …

Some notes when using a hygrometer

When using a hygrometer, to ensure the effectiveness and durability of the device, you should note the following:

• Protect the thermometer and hygrometer from strong impacts, direct contact with water, dust, chemicals.
• Do not leave the hygrometer in places with large changes in temperature, in direct sunlight, and near large heat sources (ovens, heaters).
• This device is not a toy. Keep out of reach of CHILDREN.
• Clean the hygrometer with a damp cloth. Do not use any potentially corrosive cleaning products and do not immerse the device in water.
• Improper use or disassembly of the device will void the warranty.
• In a normal environment, the hygrometer needs a period of 15 minutes to give reliable measurement results.
