InTemp® CX405 RTD Dry Ice Logger Manual
25469-A
The InTemp CX405 RTD dry ice logger is designed for Cold Chain monitoring and has a built-in
external probe that can measure temperatures as low as -95°C (-139°F). This Bluetooth® Low
Energy-enabled logger is designed for wireless communication with a mobile device. Using the
InTemp app, you can easily configure the logger, perform daily logger checks, download
reports, and monitor tripped alarms. Or, you can use InTempConnect® to configure and
download CX series loggers via the CX5000 Gateway. Use the LCD screen on the logger to check
the current temperature, logging status, battery usage, and more. Once data is uploaded to
InTempConnect, you can track logger configurations and automatically upload logger data to
build custom reports for further analysis.
