The application of temperature and humidity recorder

[2011-11-30]

Temperature and humidity recorder is to measure temperature and humidity parameters and in accordance with a predetermined time interval to be stored in internal memory, after the completion of logging its connection to a PC, use of adaptive software will store the data presented in accordance with its values, time to analyze the instrument. The instrument can be used to determine the storage and transportation, and other related processes during the experiment without any compromise product safety incidents.

Food Storage: As food storage and transportation time is not a short-term problem, but the relative balance of food preservation in the humidity to ensure food safety is an important indicator of the relative equilibrium humidity directly affect the growth of colonies. For example: In the equilibrium relative humidity of 95% RH to 91% RH range, easy to breeding colonies of Salmonella, Bolin Te bacteria, lactic acid bacteria, mold and yeast. And food preservation cycle and temperature, equilibrium relative humidity, equilibrium relative humidity value of 81% RH of the cake, the shelf life of 14 days to 27 ℃, 21 ℃ at 24 days, if the equilibrium relative humidity to 85% RH These indicators will be reduced to 8 days at 27 ℃, 21 ℃ at 12 days. Hygroscopic substances equilibrium relative humidity played a decisive role. Equilibrium relative humidity is defined as the material and the air exchange in the water is not the case, obtained by the ambient air humidity. This definition is very clear, in order to successfully store and maintain these products, environment and climate control and packing must be carefully specified. Meanwhile, too many food stored in dry conditions, its taste will be some deterioration. In view of this situation, require real-time record temperature and humidity changes, to ensure consumer food safety into the mouth.

Museum artifacts, records management: This is the product of temperature and humidity, another large area of application, and recorder in which the product is very unique. Paper files in the appropriate temperature and humidity conditions can be stored for some time more, and once the temperature and humidity conditions for the destruction of the paper will become brittle, important information will subsequently disappear, the archives record temperature and humidity is necessary, you can prevent accidents from happening. Using temperature and humidity recorder will record temperature and humidity to simplify the work, will also save the cost of cultural relics preservation, to make this work to be scientific, not subjected to excessive human disturbances. And because the use of small probes to ensure minimum damage to the works of art under the premise of cultural relics, including its color, shape, free from damage.

Experimental materials: building materials, especially concrete in the drying process, we should pay attention to the drying trend, which is one of the indicators to evaluate the product, but also provided for the construction of reliable data. Application of temperature and humidity data logger can be recorded and made available to this research side building materials, construction will provide useful help. Especially in the military construction, time is life, an accurate grasp of the concrete drying time for the pre-emptive cause the enemy, in order to effectively provide vital forces to provide a guarantee on the battlefield.
 
Agriculture and animal husbandry applications: agriculture and livestock production, especially at the production of cash crops, in its seedling stage to detailed records of temperature and humidity values. In agricultural applications, due to the harsh environment - fertilizer, manure, etc., causing the pH of the environment in which humidity drift beyond other environmental products, so that capacitive humidity sensor drift requires smaller, easy to machine calibration.
 
Climate records: temperature and humidity recorder on agriculture and weather analysis have a very prominent significance.
 
Pipeline maintenance: moisture inside the pipeline would promote microbial growth, pipe mold is so formed. This will not only affect the air flow, but also encourages the growth of bacteria. These contaminated areas pose a health risk, and ultimately leads to indoor air quality deterioration.
