Features
- This temperature and humidity data logger features an LCD for easy on-site viewing. It continuously records data from measurement points and uploads data every 10 minutes by default (adjustable). Parameters such as temperature and humidity limits, deviations, and storage settings can be configured via mobile Bluetooth. The logger has an audible and visual alarm that triggers automatically when temperature exceeds the set limits.
- Data storage can be manually controlled via buttons, including the interval for storing Bluetooth-printable data. When temperature or humidity exceeds limits (button-adjustable), an over-limit recording interval is automatically enabled (also button-adjustable).
- It has a high precision temperature and humidity measurement unit with strong anti-interference performance and a wide measurement range. The large storage chip can hold up to 65,000 records. The WiFi logger can connect to Renke’s free cloud platform for remote monitoring and SMS/alarm notifications.
- This Renke temperature and humidity data logger supports two power options: 5V DC for continuous operation or a built-in high capacity lithium battery, which can last about 40 days with 10-minute upload intervals per charge.
