What it does Shows indoor and outdoor temperature and indoor humidity on a single display so you can monitor environmental conditions at a glance. Why you need it Keeps you informed about comfort and safety: maintain healthy indoor humidity, optimize HVAC settings, and track outdoor conditions that affect plants, pipes, and stored goods. Provides early warning of frost risk with a dedicated frost point alarm, helping you take preventive action before damage occurs. Records the and lowest readings so you can review temperature and humidity extremes and make better decisions about heating, ventilation, and protection. Key features and benefits Indoor/outdoor temperature and indoor humidity display — clear, consolidated information for fast decisions. Temperature unit °C/°F changeable — use the unit you prefer or the one required for your region. Memorized MAX/MIN values for indoor/outdoor temperature and indoor humidity — review past extremes to spot trends or problems without continuous monitoring. Frost point alarm: 1°C+4°C (+30.2°F+39.2°F) — explicit threshold range to alert you when conditions approach icing risk. Practical performance notes Designed for both indoor and outdoor monitoring needs; ideal for environments where you need to compare inside conditions with outside weather. Unitswitching and MAX/MIN memory simplify longterm monitoring and seasonal transitions without extra tools. Typical use scenarios 1) Winter protection: Use the frost point alarm to get notified when temperatures approach the 1°C+4°C (+30.2°F+39.2°F) range so you can protect pipes, outdoor plants, or vehicles from frost damage. 2) Home comfort and health: Track indoor temperature and humidity to reduce mold risk, improve sleep quality, and finetune HVAC or humidifier settings. 3) Garden and greenhouse monitoring: Compare indoor (or sheltered) and outdoor temperatures and store MAX/MIN readings to assess microclimates and plan plant protection or ventilation. What to expect Functional, easytoread monitoring of indoor and outdoor temperature plus indoor humidity. Simple switching between °C and °F and convenient MAX/MIN recall for practical, actionable information. A frost point alarm calibrated to the specified 1°C+4°C (+30.2°F+39.2°F) range for timely alerts when frost is a concern.
