How to use

Tips: USB temperature and humidity data logger for food storage and transportation

The food storage and transportation is not a short time issue, but the relative equilibrium humidity is an important index to ensure food safety in the food preservation. The relative equilibrium humidity directly affects the growth of the colony. For example, in the relative equilibrium humidity range of 95%RH to 91%RH, it is easy to germinate salmonella, lactic acid bacteria, molds and yeasts. In order to successfully store and maintain these products, ambient temperature control and packaging must be carefully specified. Meanwhile, if food are stored in too dry conditions, their taste will be somewhat bad. Therefore, it needs real time record of temp and humidity changes to ensure food safety for consumers.
When refrigerated food is in long-distance transport or by shipping, how important is it to prove that the goods are always at the specified temperature and humidity at the time of receipt. Putting a temperature and humidity data logger in the warehouse at the time of shipment and turning it on can solve this problem very well. The data recorder has a precise internal clock, which faithfully records the temp and humidity data of the specified time interval. When it is taken out, it can easily connect with computer’s USB port to view the graphic file and the alarm value, and judge whether it exceeds the allowable value.
