Dual High-Precision Sensors: Equipped with both internal and external temperature and humidity sensors, offering a temperature resolution of 0.1℃ for accurate monitoring. The internal sensor is ideal for stable indoor environments (-10℃ to 60℃), while the external sensor is designed for scenarios with rapid temperature changes, such as refrigerators and storage cabinets (-20℃ to 70℃), ensuring precise monitoring in various conditions.
Dual Data Recording Modes: Supports both online recording via APP and offline recording on the device. The device can store up to 5,000 data sets locally, with a default recording interval of 30 minutes, ensuring over 100 days of data retention. The recording interval can be adjusted flexibly (from 30 seconds to 1 hour) to meet different needs.
Convenient Data Review: By pressing the temperature review button, you can quickly access historical data from the past 2/4/6/8/10/12 hours. Data can also be viewed in real-time via the APP, making it easy to monitor temperature changes at any time.
Smart Data Analysis and Export: The APP allows you to view temperature change curves, maximum and minimum values, and supports exporting data reports in EXCEL and PDF formats, facilitating data analysis and archiving.
Long Battery Life & Energy Efficiency: Designed with low power consumption, the device can run for over 6 months in always-on mode with just 3 AAA batteries, and up to 500 days in total, reducing the hassle of frequent battery replacements.
