Product purpose Simple, reliable temperature measurement across a wide working range for home, commercial, and outdoor use. Key benefits — why you need this product Accurate, dependable readings: ±1°C accuracy helps you monitor conditions where temperature control matters. High precision when it counts: 0.1°C resolution for temperatures above -20°C gives fine-grained readings for room, appliance, and equipment monitoring. Wide working range: measures from -50°C to 70°C (-58°F to 158°F), covering deep-freeze storage through hot environments. Easy, portable power: runs on a single AAA battery (not included) for flexible placement without needing a nearby power outlet. Performance and compatibility Power supply: powered by one AAA battery (not included). Compatible with standard AAA cells for convenient replacement. Resolution: 0.1°C for readings above -20°C; 1°C resolution for readings below -20°C. This lets you see small changes in common temperature ranges while still covering extreme cold. Accuracy: ±1°C across the specified range, providing consistent, repeatable measurements. Temperature measurement range: -50°C to 70°C (-58°F to 158°F), suitable for a wide variety of environments and applications. How it solves problems Prevents spoilage and damage by giving actionable temperature data for refrigerators, freezers, and cold storage. Supports safe environments by monitoring ambient temperatures where children, pets, plants, or sensitive equipment are kept. Makes outdoor and seasonal monitoring practical without needing mains power, thanks to the single AAA battery. Practical use scenarios Food safety and catering: place inside refrigerators or freezers to confirm storage temperatures remain within safe limits (-50°C to 70°C range covers typical freezer and cooler conditions). Cold-chain and medical storage: monitor vaccines, samples, or temperature-sensitive supplies where accurate tracking above -20°C (0.1°C resolution) is important. Outdoor and seasonal monitoring: check garage, shed, greenhouse, or backyard temperatures during cold winters and hot summers without requiring a dedicated power source. What to expect Portable, battery-powered temperature monitoring with clear performance specifications: single AAA battery operation, defined resolution steps, ±1°C accuracy, and a wide -50°C to 70°C (-58°F to 158°F) range. Use in any application that requires reliable temperature readings within these documented limits.
