Types of Best Hygrometer

Mankind has been able to measure humidity for more than two centuries. With the development of science and technology, new versions of best hygrometer devices appeared. Today, all hygrometers can be divided into the following types.

  1. Electrical Hygrometers
  2. Indoor hygrometer quickly measures the humidity in the room. The basis of such a device is the measurement of the constantly changing resistance of the ambient air. The layer of chloride-lithium electrolyte deposited on the plate is supplied with a low voltage from the batteries. The electrical characteristics of this sensor built into the console are constantly changing under the influence of moisture vapor in the air and fixed.

  3. Psychrometers
  4. The psychrometer in Greek means “cold measurement”. This is the main answer to the question of what measures the hygrometer. In other words, it can be used to measure the temperature and humidity of the air. Its principle of operation is based on changing the physical properties of a fluid. During this process, water evaporates. It loses energy, therefore, the temperature drops. Such a decrease is recorded with a wetted thermometer. Before using a psychrometer, you need to know that the evaporated liquid is near the psychrometer, therefore, this affects its indications.

    Its main difference from a hygrometer is in principle of operation, whose work is based on changes in the physical and chemical properties of substances when air humidity fluctuates.

  5. Dew Point Hygrometers
  6. Inside the device there is a metal mirror, which condenses moisture from the injected air under pressure. The device measures its weight and determines the level of humidity.

  7. Mechanical Hygrometers

To measure the humidity in a room, many opt for a mechanical model. It is easy to operate, its price is less than that of a digital one. However, its data may have an error. The simplest devices are not certified and do not pass verification in meteorological services. Therefore, in this case it is impossible to talk about the accuracy of the measurement. The place of their location is important for mechanical hygrometers. Most often, wall models are offered, which does not always fit into the interior.

#Electrolytic Hygrometers

These devices belong to the level of laboratory equipment. The have high measurement accuracy. The principle of operation is to change the concentration of the electrolyte deposited on the control plate.

#Capacitive Hygrometers

Sensitive sensor is a capacitor of several layers of ceramics and polymers. Typically, such devices are used to measure moisture in bulk building materials and substances. But some devices have the additional function of measuring relative humidity.

#Hair Hygrometers

With such a device, relative humidity is determined within 30% … 100%. The principle of operation is based on the properties of a non-fat human hair to change length, depending on the humidity of the air in the room. Modern devices often use polymer threads with the same properties.

#Weight (Absolute) Hygrometers

This is one of the most accurate analog devices that determines the amount of water vapor in the air in g / m3. The design consists of several U-shaped tubes filled with hygroscopic chemicals that absorb moisture from the air .

Best Hygrometer Buying Guide — What to Look at?

Today a large range of best hygrometer 2019 models is on the market of measuring instruments. They all differ in appearance, function, purpose and, of course, in price. The cost of hygrometer for sale devices that are similar at first glance may vary significantly. To buy too expensive and multifunctional unit for home use is also not efficient, as well as saving on the best hygrometer for the laboratory. So what are the parameters to choose best hygrometer 2019, and what to take into account?

There is a number of initial parameters that must be determined before buying the best hygrometer.

#Application

Before acquiring the most accurate hygrometer, it is necessary to determine the conditions under which it will be used – its basic parameters depend on it. With the wrong choice, you can quickly bring the device into disrepair or steadily get erroneous indicators that do not allow you to create the desired level of comfort of the dwelling.

When choosing hygrometers to measure the humidity of the air, look for models with a temperature meter – this will allow you to find the dew point easily. If the hygrometer is designed for home or office, it is desirable to place it on a stand from a kit or on a wall so that it is always visible.

#Home Use

It is unlikely that the utilitarian look of a psychrometric meter will decorate the interior of a luxurious living room. Digital devices are offered in a wide range, so choosing the best option will not cause difficulties. Even relatively inexpensive products of this category are capable of performing several useful functions. The room hygrometer displays the temperature besides the humidity level. Consideration should be given to the advantages of equipping with additional outdoor sensors. In practice, it may be useful to store measurement results in memory, or other additional features.

#Cigar Humidors

If you are a cigar lover, you need a humidor hygrometer to make sure you keep your cigars at the correct humidity. A cigar humidor is a storage box for smoking products. Its main task is to maintain an ideal microclimate, which is based on the optimal humidity of 68%-72%. They are made of wood, mainly Spanish cedar or walnut. It is these varieties that are famous for their ability to absorb and release moisture, and also have no sharp smell, interrupting the aroma of tobacco. But not all cigar humidors are equipped with the digital cigar hygrometer, only the more expensive have a cigar hygrometer. That’s why you need to worry of buying an independent digital hygrometer for humidor. Be sure to choose the best hygrometer for humidor that fits its size.

#Instrument Cases

If you are the owner of some musical instruments, it is very important to protect it from damaging. That’s why it’s recommended to keep them in special instrument cases. But to store them properly, you need to care about the proper humidity of the case they are stored in. So you need to place a humidity monitor inside the case.

#Terrariums

Hygrometers are also used to measure the level of humidity in a terrarium. The hygrometer is glued to the wall of the terrarium from the inside. It can track the change in humidity. If the humidity level is lower than necessary for this type of reptile, put a bathing unit in the terrarium and / or spray the ground with water.

Terrarium hygrometers can be conventional round or electronic with sensors. Also, there are thermo-hygrometers for sale models that measure temperature and humidity.

#Greenhouses

Not only people, but also plants want to breathe easily. Place a hygrometer into a greenhouse and the seedlings will not be frostbitten, and mold fungi will not deprive the long-awaited harvest. For plants growing in a greenhouse, it is very important to create the right conditions. Humidity, like soil, affects the yield of plants. The ideal level of air humidity is 50-60%, of the soil – 65-85% (depending on the plants).

#Accuracy

Budget devices and devices of the middle class can make mistakes in the performance of up to 5-10%. For more accurate devices, the permissible error is 1-3%. At the same time, the measurement accuracy drops significantly when approaching the boundary values ​​of 10% and 95%. Furthermore, the accuracy of the hygrometer depends on the following characteristics:

Range of measurements. For most models of household hygrometers it is 20% … 80%, despite the fact that the scale indicates from 0 to 100%. If the real value of room humidity falls outside this range, then the measurement accuracy deteriorates significantly. More accurate electronic devices measure indicators in the lower limit of 6-15%, for industrial devices this indicator is 2-5%, the upper limit in both cases is 95-100%.

Measurement frequency (relevant for electronic devices). For household hygrometers the value of 10-30 seconds is quite valid. The price of room hygrometers performing measurements at the level of industrial models of 0.5-1 sec. is unreasonably high, since for everyday use such frequency and accuracy is unnecessary.

Additional functionality. Most devices for domestic use are designed as multifunctional devices that can provide data on temperature, time pressure. Some models receive information from external sources. In this case, remote sensors can be installed both in other rooms and outdoors. The most advanced wifi hygrometer models are synchronized with a PC or smartphones and transmit the collected data to them for statistics or control of heating and humidifying devices.

#Power Source and Battery Life

An important factor to consider is whether the hygrometer works from a power source or from a batter. In the latter case, pay attention to the time of its operation.

#Remote Monitoring and Alerts

This is one of the beneficial features, as it gives you a possibility to monitor the device via some app and get information in time. You only need to enter some pre-set limits of the humidity in the house.

#Additional Sensor Support

In case you would like to control humidity not only in one room, you should find out whether the device has a possibility of connecting additional sensors to one system for this aim.

#User Interface

This is a pure user factor. It takes into account additional functions such as memorizing values, as well as the presence of light for working in a dark room.

#Data Logging

Think if you need to store the history of the measurements. If you like to check the figures of the past dates, then this criterion is important for you. Some hygrometers store only limited amount of data, others do not.

#NIST Certification

If you require a hygrometer with precise measurement to satisfy ISO and other regulatory body requirements, you need the one with a NIST certification. This is mainly important for industrial devices.

#Price

Remember, well-known manufacturers include mark-up for the brand in the price, although there are models of little-known companies that are not inferior in quality to brand hygrometers. Also, consider the number of features the device is equipped with. The more of them it has, the higher the price will be.
