What Is A Hygrometer?

A hygrometer is a sensitive measuring instrument. It measures one thing and one thing only. It is used to measure the relative humidity – the amount of moisture – in the air.

Hygrometers come in different styles and designs, but they fall into 2 main categories… These are digital and analog hygrometers.

For many, the best analog hygrometer comes with temperature and barometer gauges built-in, making them mini weather stations.

What Are The Different Types of Hygrometers?

There are two basic types of hygrometers. They fall under the categories of analog or digital.

Analog Hygrometers

An analog hygrometer is a device used to measure the humidity level in the air. It typically consists of a mechanical system that responds to changes in humidity, displaying the readings on a dial or a scale. The most common types of analog hygrometers are bimetallic strip hygrometers, hair hygrometers, and psychrometers.

Bimetallic Strip Hygrometers:

• Bimetallic strip hygrometers employ the concept of thermal expansion to measure humidity changes.
• The hygrometer consists of two different metal strips bonded together, each with a different coefficient of thermal expansion. Typically, brass and steel are used for this purpose.
• As humidity increases, the moisture content in the air affects the thermal properties of the metal strips. One strip expands more than the other due to its higher coefficient of expansion, causing the bonded strips to bend or curve.
• This bending motion is transferred through a mechanical linkage system to the hygrometer’s dial, which displays the corresponding humidity reading.
• Pros
  • Robust and Durable: Bimetallic strip hygrometers have a sturdy mechanical design, which makes them resistant to damage and capable of withstanding harsh environmental conditions.
  • Faster Response Time: Compared to hair hygrometers, bimetallic strip hygrometers generally have a faster response time, making them more suitable for applications where quick humidity changes need to be detected.
  • Reasonable Accuracy: Bimetallic strip hygrometers can provide reasonably accurate humidity measurements, especially when used within their specified range and properly calibrated.
• Cons
  • Limited Range: Bimetallic strip hygrometers have a more limited operating range compared to hair hygrometers. They typically work well in humidity ranges between 20% to 90% relative humidity.
  • Calibration: Like hair hygrometers, bimetallic strip hygrometers also require periodic calibration to maintain accuracy, which may involve specialized equipment.
  • Mechanical Hysteresis: Bimetallic strip hygrometers can exhibit hysteresis, which means that they may display different readings for increasing and decreasing humidity levels under the same conditions.
  • Mechanical Wear: Over time, the movement of the bimetallic strip can wear down, affecting the accuracy and reliability of the hygrometer.

Hair Hygrometers:

• Hair hygrometers utilize the principle of hygroscopic materials, where certain substances, like human or animal hair, change in length with variations in humidity levels.
• Inside the hygrometer, a bundle of hair is attached to a mechanical linkage system. As humidity increases, the hair absorbs moisture from the air and expands, causing the mechanical linkage to move.
• This movement translates into the rotation of a needle on the hygrometer’s dial, indicating the current humidity level on a calibrated scale.
• Pros
  • Wide Operating Range: Hair hygrometers can measure humidity over a broad range, typically from 20% to 100% relative humidity, making them suitable for various environments and applications.
  • Simple and Reliable: Hair hygrometers have a straightforward design and do not require a power source, making them dependable and low-maintenance instruments.
  • Slow Response Time: While this might be seen as a disadvantage in some scenarios, the slow response time of hair hygrometers can be beneficial in certain applications where rapid changes in humidity need to be dampened or smoothed out.
• Cons
  • Calibration: Hair hygrometers require periodic calibration to maintain accuracy. The calibration process can be time-consuming and may require specialized equipment.
  • Sensitivity to Contaminants: The accuracy of hair hygrometers can be affected by contaminants in the environment, such as dust, oils, or chemical fumes, which can adhere to the hair and alter its response.
  • Limited Precision: Hair hygrometers often provide humidity readings with limited precision, typically to the nearest 5% or 10%. They might not be suitable for applications that require high-precision measurements.

Psychrometer:

• A psychrometer, also known as a wet-and-dry bulb hygrometer, is an analog instrument used to measure humidity by comparing the readings of two thermometers, one of which has a wet bulb and the other a dry bulb.
• The wet bulb thermometer is wrapped with a moistened wick, and both thermometers are exposed to the air. As the water evaporates from the wet bulb, it causes cooling, and the wet bulb temperature drops below the dry bulb temperature.
• The rate of evaporation and the cooling effect on the wet bulb thermometer depends on the air’s humidity level. Higher humidity slows down evaporation and results in a smaller temperature difference between the wet and dry bulb thermometers.
• By comparing the temperatures of the wet and dry bulbs, the relative humidity can be determined using psychrometric charts or formulas.
• Pros
  • High Accuracy: Psychrometers can provide accurate and precise humidity measurements when used correctly and calibrated appropriately. They are well-suited for applications where precise humidity data is required.
  • No Power Source Required: Psychrometers do not rely on external power sources, making them portable and suitable for field use, especially the sling psychrometer variant.
  • Direct Measurement of Relative Humidity: Unlike some other hygrometer types that measure changes in material properties, psychrometers directly measure relative humidity, which can be advantageous in certain scenarios.
  • Low Cost: Psychrometers are often more affordable than some advanced digital hygrometers, making them accessible for educational purposes and in situations where budget constraints are a concern.
• Cons
  • Calibration and Skill Required: To achieve accurate results, psychrometers require regular calibration and skilled operators. Proper use and understanding of psychrometric charts and calculations are necessary to interpret the readings correctly.
  • Time-Consuming: The process of taking humidity measurements with a psychrometer can be time-consuming, especially with the traditional sling psychrometer, where multiple readings and calculations are involved.
  • Sensitivity to Environmental Factors: Psychrometers can be influenced by factors such as air currents, ambient temperature, and exposure to direct sunlight, affecting the accuracy of measurements.
  • Limited Range: Psychrometers are typically effective in moderate to high humidity conditions, and they might not be suitable for measuring very low humidity levels or extremely dry environments.
  • Bulkier Design: Traditional psychrometers, especially sling psychrometers, have a bulkier and more complex design compared to other hygrometer types, which can be inconvenient in certain situations.

Digital Hygrometers

A digital hygrometer is an electronic device designed to measure and display the humidity level in the air, generally with higher accuracy and precision compared to analog hygrometers. Digital hygrometers use various sensors and electronic components to provide real-time humidity readings.

The majority of digital hygrometers use a resistive or capacitive sensor. Electricity flows through a small piece of moisture-absorbent material that is exposed to the air. When the amount of moisture absorbed changes, the electrical properties do as well. This is the data used to calculate the relative humidity. Once the calculation is complete, a measurement is sent to the digital display which provides a numerical value. This is the humidity reading for the area.

Analog Hygrometer History

Early Developments and Inventors

The origins of hygrometers date back to ancient times when people began to recognize the significance of humidity in various aspects of life. One of the earliest known inventors of a hygrometer-like device was the Greek philosopher and mathematician, Diogenes of Apollonia, in the 5th century BCE. He created a simple device known as the “Airscope,” which was a hollow sphere filled with water. Diogenes observed how the water level in the sphere fluctuated with changes in the surrounding air’s moisture content.

In the 15th century, the renowned Italian artist and inventor, Leonardo da Vinci, also delved into humidity measurement. He designed a hygrometer using a porous material that would change its dimensions with humidity variations. However, it is believed that his invention was never built during his lifetime.

Evolution and Improvements Over Time

The true advancement of hygrometers occurred during the 17th and 18th centuries. In 1664, the Italian physician and naturalist, Francesco Folli, constructed a crude hygrometer using a pig’s bladder filled with wool. As the humidity changed, the bladder would expand or contract, indicating the relative humidity.

However, it was not until the late 18th century that the most significant developments in hygrometers were made. Swiss physicist and horologist, Abraham-Louis Breguet, is credited with the invention of the hair hygrometer around 1783. Breguet’s hygrometer used a strand of human or animal hair attached to a mechanical linkage. As humidity changed, the hair would either lengthen or contract, causing the linkage to move and display the humidity reading.

In the early 19th century, Swiss physicist Johann Heinrich Lambert improved upon Breguet’s design by incorporating a scale to quantify humidity readings accurately. This made the hair hygrometer more practical and widely adopted for scientific purposes, weather forecasting, and agricultural applications.
