Another typical application
1. food storage and transportation
As the food storage and transportation process time is not a short-term problem, but food preservation in the relative humidity is to ensure that food safety is an
important indicators, the relative humidity directly affects the growth of colonies. For example, in the equilibrium relative humidity of 95% RH to 91% RH range, easy to breed
growth of colonies of Salmonella, Bollingerella, lactobacilli, molds and yeasts. The food shelf life is also related to temperature and equilibrium relative humidity
The shelf life of a cake with an equilibrium relative humidity value of 81% RH is 14 days at 27℃ and 24 days at 21℃, and if the equilibrium relative humidity is increased to
85% RH, these indicators will be reduced to 8 days at 27℃ and 12 days at 21℃. The equilibrium RH of the hygroscopic material plays a decisive role. Equilibrium
Equilibrium RH is defined as the value of humidity that a substance obtains from the surrounding air without exchanging water with the air. This definition makes it clear that environmental climate control and packaging must be carefully specified in order to
successfully store and maintain these products. At the same time, many food products are preserved in excessively dry conditions
and their texture is somewhat spoiled. In this case, real-time recording of temperature and humidity changes is required to ensure that the food is safe for the consumer's mouth.
When shipping frozen or refrigerated food over long distances or by sea, it is important to prove that the shipment has been in the specified temperature and humidity conditions at the time of acceptance.
These disputes are resolved at the time of shipment. The solution to the dispute is to place a logger in the cargo hold at the time of shipment and activate it. The logger has a sophisticated
internal clock that faithfully records temperature and humidity data at specified intervals, and when it is removed it can be easily accessed by a computer to view the graphic file and the alarm
value, to determine if it has exceeded the permissible value, and to obtain an indication of when and for how long it has been in effect, as well as whether or not the carrier is liable for the loss. The carrier will also know immediately if it is responsible.

7. Important medical and health places
According to the "hospital clean operating room building technical specifications for comments" requirements of the operating room temperature and humidity must be controlled within a certain range:
that is, the temperature in 22...25 ℃; relative humidity 45% RH... 60% RH. suitable environment. Temperature and humidity are very important for both the operator and the patient. When
room temperature exceeds 28℃ and humidity is greater than 70% RH, it is easy to have the reaction of stuffy heat, sweating, irritability and fatigue, which will easily affect the stable mood and agile
thinking, so that the operator's technical level can't be well exerted. At the same time, the patient will also have a fast heart rate, sweating and other symptoms and increase the difficulty of surgery
degree; when the room temperature is lower than 20 degrees Celsius, only wearing a surgical gown operator will feel the cold, easy to affect the operation of the movement of the sensitivity and accuracy, especially the finger
of the subtle movements. Naked patients are more susceptible to complications such as colds due to trauma body resistance is at a low level. Indoor humidity is low, objects
surface floating dust with certain actions, such as laying sheets, opening and closing the door caused by changes in airflow and suspended in the air. The temperature difference between the inside and outside of the operating room is large, and after opening the door, the air in some
areas forms a snail flow, and the wind speed increases to about four times the original wind speed of the operating room, at which time the surface of the object adherents rapidly float in the air. According to the U.S.
CDC survey shows that the number of airborne bacteria in the operating room in 700-800cfu/m3 when there is a risk of airborne infection. From the results, the surgery
Sheet to sheet 2 hours after the air pollution is the most serious, this is the stage of surgery. Due to the effect of gravity, indoor airborne dust can settle directly onto the surgical trauma
surface, or the operator's hands or surgical instruments, so it is important to strengthen the control of air pollution in this period to prevent postoperative incision infection. These
require the health epidemiology department to confirm the compliance of each hospital's operating room through its own monitoring, and the recorder is a good way to reduce personnel
waste, and to ensure the fairness of the enforcement of the law.
8. Plumbing maintenance
Moisture in the plumbing promotes microbial growth, which is how mold forms on the pipes. This not only affects air flow, but also breeds a lot of
bacteria. These contaminated areas pose a health risk and ultimately lead to deterioration of indoor air quality (IAQ).
