Product Details

The Memory-Loc™ Cryogenic Thermometer is engineered for applications requiring highly accurate monitoring at extremely low temperatures. Its platinum RTD stainless steel probe provides dependable measurements from -200 to 105°C (-328 to 221°F), making it well suited for cryogenic freezers, biological sample storage, vaccine preservation, pharmaceutical cold storage, and laboratory research.

With storage capacity exceeding one million readings, the thermometer provides secure long-term record retention. The instrument automatically stops logging when memory is full rather than overwriting existing records, helping preserve historical data for compliance, validation, and quality assurance programs.

Smart-Alarm™ technology provides audible and visual alerts whenever temperatures move outside programmed limits. Alarm history records up to ten separate temperature excursions, including alarm occurrence and recovery information.

Temperature data can be exported directly to a USB flash drive in CSV format while monitoring continues uninterrupted. Downloaded files may also be uploaded to TraceableLIVE® for centralized recordkeeping and reporting.

The included platinum RTD probe connects through a 10-ft cable, allowing freezer and storage unit doors to remain fully closed while the display stays mounted externally for convenient viewing. Multiple mounting options support installation in laboratories, storage facilities, and production environments.

Each unit includes an individually numbered Traceable® Certificate documenting traceability to recognized national measurement standards. Guaranteed to have at least one year of calibration remaining on the certificate.
