Professional Hygrometer: an indispensable tool for humidity analysis and business success

The control of humidity is a critical factor in modern industry. Indeed, the ability to monitor the percentage of humidity is essential for the success of various production processes.

To ensure impeccable work processes, industrial hygrometers prove to be indispensable tools, capable of accurately measuring the humidity present in the air, gases, and other fluids. A professional hygrometer can provide real-time data, allowing effective monitoring and regulation of production processes.

Let’s discover how an industrial hygrometer works, what it is used for, its operating principles, and the different types available on the market.

What is a hygrometer and advantages in the industrial sector

What is a hygrometer and what is its function? This instrument is designed to precisely measure the humidity present in gases, air, and other fluids within industrial contexts. Unlike domestic hygrometers, a professional hygrometer is more accurate, sturdy, and reliable, able to withstand adverse environmental conditions, corrosive atmospheres, and dust presence.

The advantages of using a professional hygrometer in industrial contexts allow for product quality improvement and compliance with regulations.

How does a professional hygrometer work?

The operating principles of an industrial hygrometer vary depending on the technology employed. However, in general, all hygrometers base on the measurement of a physical property that changes in relation to the humidity present in the sample.

The following physical properties are commonly measured:

• dew point, i.e. the temperature at which the air saturates with water vapour and begins to condense;
• relative humidity, i.e. the percentage of water vapour present in the air compared to the maximum quantity the air can contain at the same temperature;
• absolute humidity, i.e. the quantity of water vapour present in a specific volume of air.

Once the data has been obtained, following the measurement of these physical properties, the professional hygrometer processes the information within a microcontroller. Hence, a humidity value is generated and displayed on the device screen.

The different types of industrial hygrometers and their characteristics

There are various types of industrial hygrometers, which vary depending on the technologies used. Each of them has strengths and weaknesses. In particular:

• detection of aluminium oxide (Al2O3). A technology capable of ensuring a wide range of measurements, high precision, and maximum resistance to adverse environmental conditions. An example of a hygrometer with this technology is the Dew-Point 8800;
• laser, a technology capable of offering high precision and response speed, but is less resistant to adverse environmental conditions. An example of a professional hygrometer with this technology is the Spark;
• P2O5 sensor. Wide range of measurements and resistance for medical gases. Examples of hygrometers with this technology are the MEECO WaterBoy 2, the AQUAVOLT 2 and the UBER M/i.

Factors to consider when choosing a professional hygrometer

To chose a professional hygrometer capable of meeting specific needs, one must consider not only the cost but also and above all:

• the measurement range;
• the precision and reliability of the machine;
• the resistance to environmental conditions such as extreme temperatures, dust presence, or corrosive atmospheres;
• the ease of use and the need for regular maintenance;
• any additional features (such as data recording, remote communication, or compatibility with automatic control systems);
• the presence of certifications for use in hazardous areas.
