The LogTag UTRED-16F is a professional temperature data logger that uses an external probe to accurately measure temperature in ultra-cold environments (down to -90°C). It features an LCD screen, USB port, and automatic PDF reporting capabilities, making it ideal for temperature monitoring in cold storage, deep freezers, and containers for storing vaccines, biological products, pharmaceuticals, or food.
