- Wireless monitoring system: Real-time temperature tracking with one display unit and two remote sensors. Monitor temperatures across three locations simultaneously, ideal for refrigerators, freezers, wine cellars, or indoor/outdoor spaces without messy wires. - Wide temperature range and accuracy: Measures -40 C to 60 C (-40 F to 140 F) with accuracy +/- 1 C (+/- 2 F). Robust sensors track conditions in refrigerators, freezers, basements, greenhouses, or covered patios to help maintain optimal environments for food, plants, or comfort. - Extended wireless range: Up to 100 meters (328 feet) in open areas. Position sensors where you need them while maintaining a clear signal to the main display unit for continuous monitoring without signal interruption. - Customizable temperature alerts: Set high and low thresholds with audible alarms that notify you when conditions exceed your specified range. This proactive feature helps prevent spoilage, protect sensitive items, and maintain appropriate temperatures in critical storage areas. - Use scenarios: 1) Home kitchen: monitor a refrigerator, freezer, and wine cellar from a single display. 2) Greenhouse or covered patio: maintain temperature for plants and stored produce without cables. 3) Basement storage or outdoor shed: safeguard perishables by receiving alerts if temps go out of range.
