About dh meter

Types of DH meters

A DH meter measures the moisture level or humidity in a specific environment. There are different types of these meters, and they are as follows:

  • Capacitance-based DH meter

    This type of meter utilizes the principle of capacitance to determine the moisture content present in a material. It has two electrodes that form a capacitor, and when it is placed in a material, the dielectric constant of the material changes depending on its moisture content. The more moisture present, the more change in the dielectric constant. The meter then measures the dielectric constant and gives a corresponding value of the moisture content. These meters are preferred because they are safe and do not damage the material.

  • Resistance-based DH meter

    This is a simple electrical device that measures humidity levels. It contains two metal electrodes and a hygroscopic insulating material that collects moisture. The liquid causes a change in electrical resistance, enabling the meter to give a reading of the humidity level. The more water present in the air, the lower the resistance. These meters are popular because they are affordable and easy to use.

  • Psychrometric DH meter

    This device calculates the humidity in the air by measuring the wet and dry temperatures of a bulb. It consists of a hygrometer with two bulbs, one dry and one wet. The dry bulb measures the air temperature, while the wet bulb is covered with a wet cloth that evaporates water, causing a drop in temperature. The meter has a scale that corresponds to the humidity present in the air. They are often used in HVAC applications to monitor indoor humidity levels.

  • Infrared DH meter

    This type uses infrared light to measure the moisture content in a specific material. The meter is made of a light source and a detector. When the light is directed to the material, some of the light is absorbed depending on the amount of moisture present in the material. The remaining light is reflected back to the detector, and the amount of light absorbed is proportional to the moisture content. These meters are popular because they provide fast and accurate results.

Scenarios of DH Meters

DH meters are essential tools for measuring and monitoring humidity and temperature in various scenarios and applications. Here are some common usage scenarios:
