Key benefits for validation, compliance, and quality control

Improve process control with high-resolution measurements (0.01 °C), a 60,000-point memory, and secure data capture for audits and traceability. The device supports automatic F0 and L value calculation, helping you document thermal lethality in food applications and validate critical cycles in regulated environments. Plus, the software is free, enabling easy reporting and long-term record keeping.

Typical applications

  • Steam sterilization and thermal disinfection (hospital and pharma workflows)
  • Pasteurization and thermal processing in the food industry
  • Laboratory temperature validation and data recording
  • Quality control in production lines and medium-scale manufacturing

What makes the HOT LOG HL different

  • Up to 140 °C with an internal probe for stable measurements
  • IP68 and pressure resistance up to 10 bar (fully hermetic)
  • Auto start/stop when a preset temperature threshold is reached
  • MultiLog for multiple logging cycles (up to 500, depending on interval and duration)
  • User-replaceable battery with long service life
  • USB interface via reading unit

Reference: 5005-0900
Important: the 5090-0900 reading unit is required for USB communication and data download.
