InTemp® CX405 RTD Dry Ice Logger Manual
25469-D
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. The InTempVerify™ app is also available to easily download loggers and
automatically upload reports to InTempConnect. (Note: InTempVerify is for downloading and
continuing loggers only. It cannot configure, start, or restart the loggers.) 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.
