Supported Applications
The Dwyer Series DRFT Solar Digital Refrigerator and Freezer Thermometer is designed for monitoring cold environments in refrigerators and freezers. The product overview states the unit helps monitor appliance temperature fluctuations to preserve food, medications, wines, and other items by preventing spoilage.
Operating Conditions & Performance
The Series DRFT measures temperatures from -40 to 158°F (-40 to 70°C) using a thermistor sensor. Accuracy is specified as ±1°C for the range of 0 to 50°C, and ±1.5°C for ranges of -40 to 0°C and 51 to 70°C. The unit features an LCD display with a response time of 10 s.
Operating ambient temperature is rated from 41 to 140°F (5 to 60°C). Power requirements are met by a 1.5 V AAA alkaline battery, which is installed functional and user replaceable; the unit also incorporates solar panels described as environmentally attractive, efficient, and cost-saving.
Configuration Options
The series offers configurable housing colors and optional calibration documentation:
- Housing Material: ABS case with overall dimensions of 4.5" x 1.1" x 0.6".
- Sensor Probe: Capillary length is 3.2' (1 m).
- Color Options: Available in white (Model DRFT-10) and black (Model DRFT-10-BLACK). The model number guide indicates the format DRFT-<COLOR>.
- Calibration Option: A NIST traceable calibration certificate is available using order code NISTCAL-TG.
The unit weighs 2.8 oz (80 g).
Key Product Differences
Differences between the enumerated variants are limited to housing color: Model DRFT-10 is white, while Model DRFT-10-BLACK is black. Both models share identical measurement ranges, accuracy specifications, sensor type (thermistor), and power requirements.
