Applications

Tempwit single use USB temperture data logger is important to cold chain transportation for perishable products, especially food products. The non-breaking cold chain could guarantee food products maintain high quality and optimum shelf life.
For the meat and fish products, also called frozen food, it is very important to keep the growth of microbes as low as possible by maintaining temperature threshold values.
For fruits and vegetables, the most important thing is to prevent them from ripening too early. Fruits, vegetables, and flowers are highly perishable commodities that require proper environmental monitoring in post-harvest processing to maximize freshness, quality, and shelf life from the field to the table.
The environmental condition of temperature-sensitive products must be carefully monitored and documented during handling and storage, to ensure food safety, quality, and longer shelf life, especially for highly perishable products such as produce, dairy, seafood, meat, poultry, and floral product.
The USB Temperature Data Logger is the necessary evidence for the product owner and the cold chain carrier if the cold chain performance objection is required.
Tempwit provides all kinds of temperature data logging or temperature and humidity data logging solutions to make sure every change in the whole cold chain solution will be traced and recorded. Irreversible PDF Logging, CSV temperature history, and online IOT logging in any format are available.
