![]() ![]() They are generally small in size and can often be placed on walls or ducts in industrial settings. These devices are typically designed for low dew point measurements. ![]() Aluminum Oxide HygrometersĪnother common device for dew point measurement method is metal oxide apparatuses, also known as aluminum oxide technology. Generally these sensors are used for industrial uses that require moderate accuracy. The device is not easily contaminated, and may be cleaned with ammonia and recharged with lithium chloride. In these applications, each sensor is composed of metal tubing walls saturated with lithium chloride solution and wound with wires that are connected to a power source. Industrial uses of this device include measurements for dryers and refrigeration controls. They are advantageous over electrical humidity devices because they are not easily contaminated. Lithium chloride sensors are used because of their high reliability and relatively easy construction. This process allows the device to be an equalizer of the condensation and evaporation on the surface of a mirror by using an electronic mechanism. Also, these devices are available in digital and allow for wireless readings. Modern measuring hygrometers that have developed from the first manual chilled mirror hygrometer include more elaborate models, such as “self-checking” features that allow the device to detect and react to contaminants. Inspection and maintenance can be performed with a mirror microscope, and typically the sensor can be opened manually via attached springs. Because the apparatus is sensitive, it is necessary to clean the device to ensure continual results, but it may be costly to maintain. While the mirror system is widely considered to be the most effective measurement process, its drawback is a tendency to become polluted. In addition to its use in material production (paints and glass manufacturing, for instance), the system is also effective in dry food processing. ![]() This process is generally used in laboratory practices, and for monitoring the environments of storage venues. The temperature of the mirror is measured. The process entails cooling a mirror until water vapor begins to condense on the surface. The device is considered to be a humidity transfer standard. Generally, hygrometers, or cooled mirrors, have been the conventional air measurement tools used for precise dew point measurement. Dew Point Measurement - Effective Tools: Hygrometers Because of its vital role in vast processes, precise dew point measurement tools have become a fundamental utility in everyday industrial functions. It is also important in determining potential corrosion in metals, and in numerous chemical manufacturing processes. For example, the dew point, defined as the temperature at which air moisture begins to condense, is a significant factor in HVAC, heating, venting and cooling technologies. Environmental conditions can determine the effectiveness of many industrial applications, which is why dew point measurement to monitor the dew point is essential in many trades. ![]()
