Dry Ice Temperature Monitor for Ultra-low Temperature Food Storage

Premium tuna relies on strict cold chain management to retain its nutrients, prime texture and raw sashimi quality. Regular freezers run at -18°C to -25°C, but tuna for sashimi needs far colder storage — typically -50°C to -60°C for long-term keeping. These ultra-low temperatures slow bacteria, enzyme breakdown and fat spoilage, so the tuna stays sellable much longer. Freshliance’s Atlas Log-IUT dry ice temperature monitor is built for such cryogenic temperature monitoring.

Atlas Log-IUT dry ice logger supports configurable parameters before start. Up to six high or low alarms can be made based on single event or accumulative time, helping warehouse managers to distinguish between minor, transient fluctuations and prolonged temperature excursions that genuinely compromise product quality. With our dedicated configuration software, users can set each device in accordance with their corporate quality control system and supply chain requirements.

The dry ice logger features an IP65 rating and ultra-low temperature resilience, and the 96mm*44mm*15mm housing easily slips into standard packaging or containers. To monitor data, users can directly place the dry ice temperature monitor into walk-in cold rooms, deep freezers and other ultra-low temperature environments. 

The sensor provides precise temperature measurement with ±0.5℃ accuracy and 0.1℃ resolution across the range of -60℃~70℃, meeting the rigorous quality inspection and audit standards that tuna cold-chain operators demand. The battery also maintains exceptional stability throughout the freezing range down to -60℃. It runs for up to 90 days continuously, ideal for long-term, maintenance-free monitoring.

The onboard memory ensures secure data storage of Max. 35,000 time-stamped, tamper-proof readings. The PDF/CSV reports can be automatically generated on a computer with USB connection, supporting routine quality checks, HACCP record-keeping, and cold storage compliance verification. Temporary PDF reports can be accessed on demand during recording, without data gaps or recording interruptions.

With exceptional reliability, Atlas Log-IUT dry ice temperature monitor is well suited for cold chain storage and transportation monitoring of biological samples, active pharmaceutical ingredients, and premium frozen seafood, etc. The built-in NIST-traceable calibration certificate ensures full measurement traceability and regulatory compliance.
