Handheld temperature probes are vital tools for food safety, disease prevention, and regulatory compliance. They help ensure food stays out of the danger zone and that harmful pathogens are effectively eliminated.

The LPT01 is a LoRaWAN-enabled food temperature probe designed for remote monitoring of food temperature. It automatically records temperature data and uploads it to an IoT platform, helping meet food safety regulations while reducing manual documentation errors and saving time.

With real-time alerts for temperature deviations, the LPT01 enhances food safety by allowing swift corrective actions to prevent potential hazards. Its long-range LoRaWAN connectivity ensures reliable data transmission and simplifies deployment and maintenance—dramatically lowering operational costs for food safety management.
