Features 1. Wide Temperature and Humidity Range: This LED display temperature and humidity detector accurately measures temperature from -20°C to 80°C with an accuracy of ±1.0°C and humidity from 0% to 100% RH with a tolerance of ±4% RH. This broad range makes it suitable for various environments, including home, office, and industrial applications. 2. High Accuracy Sensor Technology: Equipped with a high accuracy SHT C3 sensor, this temperature and humidity meter offers a sampling rate of up to 2 times per second, ensuring fast and reliable readings. This feature supports real-time monitoring of changing conditions, delivering precise data when needed. 3. Convenient Hideaway Stand: The thermometer and hygrometer includes a concealed retractable stand on the back, enabling stable placement on desks or flat surfaces. This design enhances usability and accessibility in both home and office settings. 4. Customizable Alarm System: Users can set high and low thresholds for temperature and humidity. If measurements exceed these limits, ble alarms and visual indicators are activated. This alert system helps monitor environmental conditions and supports timely responses. 5. Extended Probe Capability: The device includes an external temperature and humidity probe with a 5-meter cable, allowing flexible placement in hard-to-reach areas while maintaining accurate measurements. It also features a 3.5mm output interface compatible with standard jacks for connecting optional 5-12V alarm speakers (not included), enhancing its monitoring functionality.
