Shopping guide

hygrometer type

During the comparison of hygrometers that you decide to carry out, the first thing you should take into account is the type of hygrometer that you want to acquire, since in the market you can find a variety of these with totally different characteristics and designs. In this sense, you should decide on an analog or digital hygrometer, taking into account that they are totally different when it comes to putting them into operation.

It should be noted that analog hygrometers are characterized by the precision they offer you with each humidity and temperature measurement. Also, this task is usually carried out almost instantly, which is why they are the favorites of many users. However, you must take into account the fact that they require certain types of maintenance and calibration periodically so that you can enjoy optimal and proper operation.

For its part, digital hygrometers are a very practical product that begins its work from the use of batteries that will supply the appropriate energy for its operation. These are also capable of giving you an accurate measurement and, unlike analog models, they do not need to be calibrated or require any type of maintenance. However, its reading is usually a little slower. Therefore, deciding on one of these models will depend largely on the degree of expectations you have for easy, comfortable and safe use.


During the realization of this guide to buy the best hygrometer available on the market, it is also necessary that you can take into account the design available in its structure.

Frequently asked questions

Q1: What is a hygrometer with a relay output used for?

A hygrometer with relay output allows, in the dehumidification process, to activate the output when the humidity values ​​are greater than or equal to the value established in the product, while in humidification mode, when the humidity levels are greater than or equal to the set value, the relay will turn off.

Q2: How far can a high-precision hygrometer go?

High-precision hygrometers can give you a very accurate reading of the temperature and humidity levels available in the environment. Although there are many models on the market, each one is capable of offering you a totally different measurement range. Therefore, we consider that high-precision hygrometers can give you a humidity reading of 10% to 99%, while in the case of temperature they could offer you a reading that goes from 0°C to 50°C or -50°C to 70°C.

Q3: What are the advantages of a temperature compensated hygrometer?

Hygrometers with temperature compensation represent a considerable level of quality, since they are much more practical and functional, since you could enjoy a much more accurate temperature reading during each use that you decide to give them. For its part, with the help of a temperature compensator it would be much easier to obtain the appropriate temperature values ​​in certain spaces.

Q4: How does an analog hygrometer work?

An analog hygrometer is based on a very basic type of operation where you will have to gather some hair in the form of a cord to measure humidity levels. In this sense, once the hygrometer measures it, a needle indicates the amount of humidity available in the environment.

Q5: What is a resistive hygrometer?

Among so many hygrometers available on the market, you could also find those of the resistive type that stand out for being a product whose resistance changes with the variations that occur in the relative humidity that exists in the air and that are generated in contact with some element. This type of hygrometer, in general, is made up of two laminated metal electrodes that are positioned on a plastic form.

Q6: Which is better, hygrometer or hydrometer?

Before qualifying any of these measuring instruments as the best, it is important that you know what each one is for by first considering the fact that they are designed to measure different component levels. Thus, when we talk about a hygrometer, we refer to a device that is responsible for measuring the humidity available in the air, therefore, it is used to know the degree of humidity that could exist in a specific place.

For its part, the hydrometer is also a measuring instrument that, unlike the hygrometer, serves to know the density level of a liquid according to the density level of water. In this way, each instrument will be better according to the type of task you need to carry out.

Q7: How to make a digital hygrometer?

To create a hygrometer, you will need materials such as a bottle, cotton, two thermometers, tape, a utility knife, and water. Next, the first thing you should do is place cotton around the bulb of one of the thermometers with adhesive tape, taking into account the fact that you will have to leave some excess cotton in it. Then, you will take the plastic bottle and make a small hole right at the bottom with the help of the cutter.

Now, insert the remaining cotton from the thermometer into the hole you have made and fasten said thermometer with adhesive tape to the structure of the bottle. This way, all you have to do is place the second thermometer on the other side of the bottle and secure it with tape. Only then, you can now proceed to fill the water bottle right up to where the cotton is and in this way you will be able to know the humidity of the water that will be marked on the first thermometer, while the temperature of the water will be marked on the second thermometer. air.

Q8: Which is better, an analog or digital hygrometer?

Although analog and digital hygrometers are designed to carry out the same task, the truth is that analog models are more accurate and of quality with each use. These same ones are capable of giving you a measurement of the humidity available in the environment almost instantaneously and with an almost imperceptible margin of error, unlike digital hygrometers, which usually take much longer to provide you with the information you need.
