High Precision and Wide Measurement Range:The indoor temperature range is from -4°F to 158°F (-20°C to 70°C), and the outdoor temperature range is from -58°F to 158°F (-50°C to 70°C). The humidity range is from 10% to 99%. The temperature accuracy is ±1.8°F (±1°C), and the humidity accuracy is ±5% RH. The humidity conditions are as follows: Wet when humidity is above 70%; Comfortable when humidity is between 40% and 70% and the temperature is between 20°C and 28°C; Dry when humidity is below 40%.
3 Wireless Sensors: This wireless indoor/outdoor thermometer, equipped with remote sensors, allows you to display readings from up to 4 different locations at the same time. You can easily monitor the temperature and humidity of your entire home, basement, or greenhouse with confidence using our digital gauge
USB and Battery Powered: When powered by batteries, the backlight stays on for 15 seconds. However, when connected to the USB cable, the backlight remains on continuously and allows you to adjust between three brightness levels: high, low, or off
Historical Temperature Tracking: This wireless weather station tracks both 24-hour and all-time maximum and minimum temperature records, which can be reset when needed. It ensures accurate and reliable monitoring of temperature changes
Versatile Mounting Options: The indoor/outdoor thermometer offers three different mounting options: a tabletop stand, a magnetic back, and a hanging hole. This allows you to place the thermometer wherever you need, such as in the bedroom, nursery, wine cellar, basement, garden, greenhouse, grow tent, or office
