Food storage and transportation, because the time of food storage and transportation process is not a short-term problem, but the relative balance of humidity in food preservation is an important indicator to ensure food safety. Relatively balanced humidity directly affects the growth of colonies. For example: In the range of 95%RH to 91%RH, the number of colonies that can easily grow is Salmonella, Pollinella, Lactobacillus, Mold, and Yeast. The food preservation cycle is also related to temperature and equilibrium relative humidity. The cake with a relative humidity of 81% RH has a shelf life of 14 days at 27°C and 24 days at 21°C. If the equilibrium relative humidity is increased to 85% RH, these The indicator will be reduced to 8 days at 27°C and 12 days at 21°C. The equilibrium relative humidity of hygroscopic substances plays a decisive role. Balanced relative humidity is defined as the value of humidity obtained from the ambient air when the substance is not exchanged with water in the air. This definition is very clear, in order to successfully store and maintain these products, the environmental climate control and packaging must be carefully specified. At the same time, many foods are kept too dry and their taste will deteriorate. To address this situation, it is required to record changes in temperature and humidity in real time to ensure that food safety enters consumers' mouths.

When long-distance transport or sea foods are frozen and refrigerated, it is very important to prove that the goods are always at the specified temperature and humidity conditions when they are received. The solution to the controversy is to place a recorder in the cargo compartment and start it at the time of shipment. The temperature and humidity recorder has a precise internal clock that faithfully records the temperature and humidity data for a specified time interval and can be easily retrieved when removed. Use the computer to view the graphic files and the alarm value to determine whether the allowable value is exceeded, when and when the duration can be easily obtained, and whether the carrier’s responsibility is immediately known.
Museum heritage, archive management:
This is another big area of ​​application of temperature and humidity products, and the temperature and humidity recorder is a very special product in it. The paper in the archive can be stored for some time under conditions of suitable temperature and humidity, and once the temperature and humidity conditions are destroyed, the paper will become brittle, and important data will disappear. Therefore, it is necessary to record temperature and humidity in the archives. Prevent the occurrence of malignant accidents. The use of a temperature and humidity recorder will simplify the work of recording temperature and humidity, and will also save the cost of keeping cultural artifacts, so that this work will be scientific and will not be disturbed by excessive human factors. At the same time, due to the use of tiny probes such as the Hygroclip sc04, which ensure the minimal damage to the artwork, artifacts, including their color and shape, are not destroyed.
Building Materials Experiment:
In the drying process of building materials, especially concrete, we should pay attention to its drying tendency, which is one of the indicators for product evaluation, and it also provides reliable data for construction workers. The use of a temperature and humidity recorder can record this data and provide it to the building materials researcher, which will provide useful help for the construction. Especially in military buildings, time is life. Accurately grasping the concrete drying time is the first step to the enemy. It provides guarantee for the effective supply of living forces to the battlefield. This function is accomplished by Hygrolog+HygroClip sc04.
Agriculture and animal husbandry applications:
In agriculture and animal husbandry production, especially for the production of some economic crops, the temperature and humidity values ​​must be recorded in detail at the seedling stage. In agricultural applications, due to the harsh environment - fertilizers, excrement, etc. caused by the acid and alkaline environment so that humidity products drift more than other environments, which requires less humidity sensitive capacitance drift, the whole machine is easy to calibrate. Climate records: The Hygrolog temperature logger is of great significance for agricultural and meteorological analysis.
Building acceptance:
Mainly reflected in the acceptance of smart buildings. Due to the large number of inspection and acceptance projects in the construction industry, in addition to HVAC indicators, other construction departments such as ray intensity and formaldehyde concentration are required to be monitored in accordance with human health indicators. These indicators are directly related to human health. If these indicators are unclear, the testers have rushed into these sites and recorded them for a long period of time. They are irresponsible for the personal health of the testers, and the application logger will ensure that the test is performed while obtaining reliable data. The personal safety of personnel provides maximum protection.
Important health care facilities:
According to the requirements of the “Construction Technical Specifications of the Hospital Clean Operation Department Consultation Draftâ€, the temperature and humidity of the operating room must be controlled within a certain range: the temperature is 22-25°C; the relative humidity is 45%RH-60%RH. Appropriate ambient temperature and humidity are very important to both the operator and the patient. When the room temperature exceeds 28°C and the humidity is more than 70%RH, it is prone to reactions such as stuffy heat, sweating, irritability, and fatigue, which easily affects stable mood and agile thinking, so that the operator's skill level can not be well exerted. At the same time, the patient will also experience rapid heart rate, sweating and other symptoms and increase the difficulty of the operation; when the room temperature is lower than 20 degrees, the operator who only wears the surgical gown will feel cold, which may affect the sensitivity and accuracy of the operation, especially The subtle movements of the fingers. Bare patients suffer from flu and other complications due to traumatic body resistance at a low level. The humidity in the room is low, and the dust on the surface of the object floats in the air due to some movements, such as a single shop, a switch door, etc. The temperature difference between the inside and the outside of the operation room is large. After the door is opened, the air in some areas forms a vortex flow, and the wind speed increases to about 4 times the original wind speed of the operation room. At this time, the attachments on the surface of the object rapidly float in the air. According to a survey conducted by the United States CDC, the number of planktonic bacteria in the air in the operating room is at risk of airborne infection at 700-800 cfu/m3. From the results, it can be seen that the air pollution was the most serious at the time of surgery from the shop to the shop, and it was at the surgical stage. Due to the effect of gravity, dust in the room can directly sink to the surgical wound or the operator's hand or surgical instruments. Therefore, it is important to strengthen the control of air pollution during this period to prevent postoperative wound infection. These require the health and epidemic prevention departments to confirm the compliance status of operating rooms in each hospital through their own monitoring. The recorder is a good method, which reduces the waste of personnel and ensures the fairness of law enforcement.
Pipeline maintenance:
The moisture in the pipeline promotes the growth of microorganisms. Molding on the pipeline is thus formed. This will not only affect the flow of air, it will also breed a large number of bacteria. These contaminated areas pose a threat to health and eventually lead to deterioration of indoor air quality (IAQ, Indoor Air Quality). Oy Lifa used ROTRONIC temperature and humidity recorders and a mini truck to find a very good way to study pipeline conditions, remote video equipment and inspection pipelines.
