Description
The ETI 17-830225 Digital Refrigerator/Freezer Thermometer is a professional dual-probe instrument designed for precise temperature monitoring in refrigeration units. This versatile thermometer features both an internal sensor for measuring ambient temperature and a water-resistant external probe with a 1-meter cable for simultaneous monitoring inside refrigerators or freezers. The thermometer unit is conveniently mounted on the exterior of the appliance, while the probe is secured inside using the included suction cup or mounting bracket, enabling temperature readings without opening doors and compromising cold storage.
Ideal for HACCP compliance and food safety routines, the 17-830225 includes a programmable audible alarm that provides immediate warning when temperatures fall outside safe preset limits, allowing for rapid corrective actions to prevent food spoilage. The max/min recording function enables tracking of temperature extremes over time, providing documented evidence of temperature control for food safety management systems. The clear digital display shows both ambient and appliance temperatures simultaneously, making routine temperature checks fast and efficient. This reliable instrument is ideal for restaurants, catering companies, grocery stores, and any facility where maintaining correct food storage temperatures is critical for safety and regulatory compliance.
