description
Constructed with high-density non-fluorinated polyurethane foam insulation, this -40°C medical freezer ensures exceptional thermal retention. An independent inner door minimizes cold air leakage for consistent internal temperature stability. A standard 25mm test hole is included for versatile monitoring needs. Operating within a wide voltage range of 187V~242V, it features power failure protection and a startup delay function to prevent device damage. A dedicated door lock prevents unauthorized access, while a large digital screen enables intuitive temperature monitoring.
