Rating of the best hygrometers (humidity sensors) for 2020

In the toolbox of professional builders there are various devices that allow you to track comfortable conditions for installation, one of which is a hygrometer. It is also used in other fields of activity, as well as in everyday life. The quality of measurement is influenced by many factors, on which the accuracy of the device will depend. Attention is given to an overview of the best hygrometers for 2020 with their pros and cons, price segment and technical properties.

Types of hygrometers and their features: selection criteria for devices

How to choose a humidity sensor? To begin with, you should familiarize yourself with the types of devices and their purpose, after which the choice will be much easier. The table shows the classification of hygrometers and their features.

Table - "What are the moisture sensors?"

Functional classification:	Description:	Application:
Capacitive:	condensates with air act as a dielectric in the gap	measuring the amount of water contained in solids
Resistive:	is a structure with two electrodes deposited on a substrate, on top of which a material with low resistance is applied	measurement of water in the environment
Thermistor:	a pair of nonlinear identical electronic components (thermistors), the resistance of which depends on their temperature	research activities
Optical:	the most accurate but expensive device. Measurements are carried out thanks to an LED in a simple circuit that shines on a mirror surface, from which light is reflected, falling on the photodetector	in many fields of activity, in everyday life
Electronic:	work on the principle of changing the concentration of electrolyte, cover any electrical insulating material	are in great demand among summer residents, making measurements of soil moisture to set up an irrigation system

Optical and electronic moisture sensors are in great demand.By their characteristic properties, they are more accurate, resistant to various kinds of interference.

These devices can be hung on walls, stand separately on the surface, or you can simply hold the sensor in your hand and take measurements. Modern wall-mounted devices include two scales: one for temperature, the other for humidity. Installation of such hygrometers (another name - "psychrometer") is popular with meteorological people, flower growers and gardeners.

What to look for when buying a humidity sensor? Some recommendations for choosing:

• Application area;
• Mechanical or electronic;
• Hardware (for example, operating temperature range);
• Installation type;
• Which company is better: foreign or domestic production;
• Medium price segment.

Having chosen a hygrometer model for purchase, it is important to listen to the advice of professionals (store employees - sales assistants), study customer reviews, and view reviews on the Internet.

Where to buy a moisture meter? The easiest and most convenient way is to buy through an online store. The place of sale also depends on the purpose of the appliance. If you need to measure the temperature and humidity of the air, they purchase thermo-hygrometers, which can be found at the pharmacy. For research purposes, the construction industry and agricultural work, a psychrometric hygrometer is needed that measures the relative humidity of the air and its temperature, it can be bought in hardware stores. For a narrow focus - to measure air humidity, buy a hygrometer.

Thermohygrometers are conventionally divided into two types: for operational control of parameters (possibly with a remote probe) or continuous monitoring of the indoor microclimate.

All electronic humidity sensors are battery operated. With long-term operation, the battery wears out, as a result of which the reading error increases, therefore it is necessary to replace the batteries with new cells in a timely manner. It is convenient to do this if there is a battery charge indicator.

Customer reviews, video reviews on hygrometer models and advice from consultants will help prevent mistakes when choosing. Connecting devices shouldn't be difficult, and the function settings are described in the operating instructions. If the company is foreign, the insert is printed in several languages.

Which hygrometer is better to buy is up to you.

Output

No construction is complete without hygrometers. These devices have gained importance in everyday life, laboratory research, agricultural activities and other spheres of human life. They are capable of measuring moisture levels in liquid, gaseous and solid substances.

Optimal air humidification for humans is 45-60 percent. As soon as the indicators are below or above the desired range, the body begins to painfully perceive the situation around itself.

According to buyers, the most accurate are electronic hygrometers of Russian and foreign production. They can operate in negative and positive temperature ranges (depending on the model). Air humidity is measured only in positive intervals. Devices with a step of one division and a reference point from zero are the most reliable. Budget options - wall-mounted hygrometers for baths or rooms made of wood or plastic. The table lists the most common humidity sensors for the current year.
