InTemp CX400 Series, Manual

InTemp® CX400 Series Temperature Logger Manual 

19996-P 

InTemp CX400 series loggers measure temperature in indoor monitoring applications. Designed 
to meet World Health Organization (WHO) and Centers for Disease Control and Prevention 
(CDC) guidelines, this logger is ideal for clinical applications, such as vaccine storage and 
pharmaceutical manufacturing. 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 with one of four preset profiles designed for ambient storage, clinical refrigerator, 
freezer, or refrigerator monitoring or you can set up a custom profile for other applications. 
You can also quickly 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. Use the built-in LCD screen on the logger to 
check the current temperature, daily maximum or minimum temperatures, logging status, 
battery use, 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. The CX402 model uses a 2- or 4-meter probe and is available with a 5, 15, or 30 mL 
glycol bottle (bottle holder included). It also contains an internal sensor for ambient 
temperature monitoring. The CX403 model is available with an internal sensor only.
