Fisherbrand 15-077-721 Traceable Refrigerator Freezer Plug Thermometer 5 ml Bottle Probe -50 C to 70 C

The Fisherbrand Traceable Refrigerator/Freezer Plus Thermometer, MPN 15-077-721, is a digital temperature-monitoring instrument designed for refrigerators, freezers, incubators, water baths and heating blocks. It uses a temperature-buffered sensor sealed in a 5 mL bottle of glycol solution to monitor temperature while reducing the effect of rapid ambient changes, such as those caused by opening a refrigerator door. Minimum/maximum memory and user-settable high and low alarms support temperature monitoring over extended periods.

Technical Performance & Design

• Core Function: Measures and monitors temperatures in laboratory, refrigeration and temperature-controlled storage environments.
• System Role: Provides temperature readings and alarm alerts to support monitoring of refrigerators, freezers, incubators, water baths and heating blocks.
• Temperature Range: -50 to +70°C (-58 to 158°F).
• Resolution: 0.1 degree.
• Accuracy: ±0.5°C.
• Temperature-Buffered Probe: Sensor is sealed in glycol solution inside a 5 mL round bottle to buffer the sensor against rapid temperature changes.
• Bottle Design: The vaccine-style bottle mimics vaccine temperature and fits in a vaccine tray.
• Minimum/Maximum Memory: Records high and low temperature readings for review after an extended monitoring period, including overnight or weekend intervals.
• Alarm Functions: High and low temperature alarm thresholds are user-settable.
• Monitoring Applications: Suitable for monitoring temperature-controlled environments, including vaccine storage and laboratory equipment.
• Integration Notes: Intended for temperature monitoring in the listed environments. Mounting arrangements, probe cable length, display dimensions and power requirements were not provided.

Key Benefits for Maintenance / Use

• Temperature Monitoring: Supports routine monitoring of refrigeration, freezer and laboratory equipment temperatures.
• Buffered Measurement: The glycol-filled bottle reduces the influence of rapid air-temperature fluctuations, including changes when a refrigerator door is opened.
• Historical Extremes: Minimum/maximum memory helps identify temperature excursions that occur between manual checks.
• Alarm-Based Monitoring: Adjustable high and low alarms provide alerts when temperatures exceed configured thresholds.
• Vaccine Storage Support: The 5 mL bottle design is intended to mimic vaccine temperature and fit in a vaccine tray.
• Operational Oversight: Supports temperature-control checks for laboratory storage, sample handling and other temperature-sensitive applications.
