If you live in a place that has constantly humid and has an unbalanced moisture level in the air, then it can make you tired and sick. To ensure the best health of family members, it becomes very important to find out ways to effectively control the moisture levels in the air. Hygrometers are the best answer to solve this problem.

If you are in the market to search for the best hygrometer, then you must have a good knowledge of hygrometer, its working, and features. Along with a basic introduction of the hydrometer, this article provides you information about the different hygrometer tools that will help you form the right decision.

What are Hygrometers?

Hygrometers are a beneficial tool that is used in the calculation and calibration of pressure and temperature change. It helps in the calculation of the levels of moisture present in the air. These devices are beneficial in office and homes buildings. They are even useful in manufacturing and industrial processes where little modifications in humidity can impact the materials that are being produced.

Areas of application of hygrometers

Hygrometers perform an amazing function in homes, manufacturing plants, offices, research labs, hospital environments, food production facilities, drying processes, greenhouses, incubators, textile, paper and museums industries.

Different types of hygrometers

Let us explore the different kinds of hygrometers that are used in different types of environments.

Hair-tension hygrometers

Displacement sensors use cellulose, nylon or hair to calculate contraction and expansion caused due to humidity. These hygrometers are fairly affordable and immune to contamination.

These highly efficient hygrometers have got fibers in them that connects with dials. They cause displacements of gauges and needles as they contract and expand. These meters are very much useful for the measurement of humidity in instrument cases, homes, basements, attics, and terrariums.

Metal paper-based coil hygrometers

These devices are inexpensive in nature. They are used to evaluate moisture where absolute precision is not needed. A salt-impregnated paper gets joined to a metal wire. It changes its structure due to the loss or absorption of moisture. This causes the wire to move a dial or needle. It gives only 10 percentage of precision as these hygrometers easily indicate humidity changes without being full 100-percent precise.

Digital hygrometers

Digital devices are designed for a specific range of humidity. Some of the best digital hygrometer for the measurement of humidity levels are:

• SensorPush Wireless Thermometer.
• ThermoPro Digital Wireless Hygrometer
• AcuRite Indoor Humidity Monitor
• Xikar Rectangular Shaped Digital Hygrometer
• MIEO Round Shaped Digital Hygrometer

Humidity cards

Humidity cards are the simplest means to calculate moisture. It changes its color to signal when the humidity levels fall below the range. This hydrometer has spots in it that have cobalt chlorine solution in them and several additives that covers an extensive range of moisture conditions. Some cards even have several spots that help in covering larger humidity ranges. Cards have the ability to calculate 5 percentage to 95 percentage of relative humidity.

Electrical hygrometers

Electrical hygrometers form their calculations on the basis of modifications in capacitance or electrical resistance. The most precise kind of an electrical hygrometer pass gas on a moisture-absorbing material.

This helps in determining the amount of water that gets absorbed by evaluating the gas weight prior and post the process. Electrical hygrometers work by adsorbing or absorbing water.
