  1. Household Thermometer and Hygrometer Digital Sensor is important to cold chain transportation for perishable product, especially the food product. Non-breaking cold chain could guarantee food product to maintain high quality and optimum shelf life.
  2. 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.
  3. For fruits and vegetables, the most important thing is to prevent them 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.
  4. The environmental condition of temperature-sensitive products must be carefully monitored and documented during handling and storage, to ensure food safety, quality and a longer shelf life, especially for highly perishable products such as produce, dairy, seafood, meat, poultry and floral product.
  5. Household Thermometer and Hygrometer Digital Sensor is a necessary evidence for the produce owner and the cold chain carrier if the cold chain performance objection is required.
  6. Freshliance provide all kinds of temperature data logging or temperature and humidity data logging solutions to make sure every change in whole cold chain solution will be traced and recorded irreversible, PDF Logging, CSV temperature history, online IOT logging in any format are available.
