Application of USB temperature and humidity recorder in cold chain transportation
People's daily life is closely related to the temperature and humidity of the surrounding environment. As people's requirements for material levels are increasing, all walks of life have higher and higher requirements for temperature and humidity. Especially in the transportation of vaccines and medicines, the temperature control requirements are very strict.

In cold-chain logistics and transportation, temperature and humidity have a great impact on food and drugs. Higher temperatures will cause the refrigerated items to spoil and deteriorate during transportation. At the same time, temperature-sensitive drugs are also likely to cause drug denaturation and failure.

Functional characteristics of Cos-03-*large screen USB temperature and humidity recorder

(1) The device adopts a large LCD screen, which can display real-time temperature and humidity values, remaining power, and stored Data quantity and system time can intuitively monitor temperature and humidity values u200bu200bduring loading and unloading.

(2) It has an alarm function, because it has a built-in buzzer, once the value exceeds the limit, a high-decibel alarm can be issued, reminding the supervisor to take measures to keep the temperature within the specified range;

(3 ) It has the function of timing recording time period, and the time of equipment recording from start to stop can be set. If multiple recorders are used in one transportation, it can ensure that all equipment starts and ends recording at the same time to ensure the unity of data ;

(4) Cold chain logistics companies can export the stored data in EXCEL, TXT, PDF and other formats through a USB cable to make reports to customers. The device stores 260,000 by default, which can be expanded to 2.08 million.

(5) Adopt large-capacity rechargeable lithium battery, which can be used continuously for 1 year on a single charge, which saves the trouble of using first charge for enterprises.

In the process of cold chain transportation, the use of temperature and humidity recorders can monitor the temperature throughout the logistics process to ensure the temperature. It can also provide data recording, over-standard alarm and report services to ensure that the transported goods can be smoothly accepted by customers. It improves the ability of logistics enterprises to control temperature and humidity, and enhances the competitiveness of enterprises.

USB temperature and humidity recorder is widely used in cold chain logistics to monitor and record the temperature and humidity data of food, medicine, chemical supplies and other products in the transportation process, and is widely used in storage monitoring, such as refrigerated containers, cold storage and experiments Room etc.

Application in food storage and transportation

Since the food storage and transportation process time is not a short-term problem, the relative equilibrium humidity in food storage is an important indicator to ensure food safety. Relative balance Humidity directly affects the growth of colonies. For example: in the equilibrium relative humidity range of 95[%]RH to 91[%]RH, the colonies that are easy to breed are Salmonella, Pollindella, Lactobacillus, Mold and Yeast. The food storage cycle is also related to temperature and equilibrium relative humidity. A cake with a balanced relative humidity value of 81[%]RH has a shelf life of 14 days at 27℃ and 24 days at 21℃. If the equilibrium relative humidity is increased to 85[%] ]RH, these indicators will be reduced to 8 days at 27°C and 12 days at 21°C. The equilibrium relative humidity of the hygroscopic substance plays a decisive role. Equilibrium relative humidity is defined as the humidity value obtained from the surrounding air when the substance and water in the air are not exchanged. This definition is very clear. In order to successfully store and maintain these products, environmental climate control and packaging must be carefully specified. At the same time, when many foods are kept too dry, their taste will deteriorate. In response to 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 transportation or sea transportation of frozen and refrigerated food, it is very important to prove that the goods have been in the specified temperature and humidity conditions when receiving them. The way to resolve disputes is to put a PeopleSoft temperature recorder in the cargo hold at the time of shipment and start it. It will faithfully record the temperature and humidity changes during the entire transportation process, and will immediately know whether the carrier is responsible. At present, KFC and other well-known fast food companies are using temperature recorders.

Application in the cold chain of vaccines

In the cold chain storage and transportation of vaccines, vaccines and other biological products from the finished product warehouse of the pharmaceutical factory to the cold chain storage and transportation of vaccination to the relevant population, the environmental temperature The monitoring records can confirm its quality and ensure the effect of immunization. The temperature recorder solves this problem conveniently and reliably.

Different vaccines and vaccines have different requirements for storage and transportation environment temperature. To ensure the safety of bacteria and vaccines during storage and transportation, the entire process of testing and recording the ambient temperature during storage and transportation must be carried out, and the testing records should be fully automated, and there should be no human factors to improve the data. reliability. The high-quality and high-precision temperature recorder can perfectly complete this function, because it can record for a long time without external power supply.

Application in the management of museum cultural relics and archives

This is another area of u200bu200bapplication of temperature and humidity recorders. Archival paper can be stored for more time under suitable temperature and humidity conditions. Once the temperature and humidity conditions are damaged, the paper will become brittle, and important information will also disappear. It is necessary to record the temperature and humidity of the archives. Prevent the occurrence of vicious accidents. The use of the PeopleSoft temperature and humidity recorder will simplify the work of temperature and humidity recording, and will also save the cost of cultural relic storage, so that this work can be made scientific and will not be interfered by too many human factors.

Application in the laboratory

In the fields of medicine, biochemistry, instrument calibration, agriculture, construction and electrical appliances, laboratory environmental conditions directly affect the results of various experiments or tests. It requires accurate and reliable monitoring instruments to provide accurate environmental parameter data.
