Continuous temperature monitoring for refrigeration and cold storage.

The Blue Gizmo BG668 Digital Probe Thermometer is designed to help maintain safe temperature zones in commercial refrigerators and freezers. With an external display and wired waterproof probe, it allows operators to monitor internal appliance temperatures without opening the door — reducing temperature fluctuations and supporting food safety compliance.

The programmable high/low alarm alerts staff when temperatures move outside preset limits, helping protect stock and maintain HACCP standards.

Built for hospitality, catering, and foodservice environments.
