InTemp® CX400 Series Temperature Logger Manual

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

LCD Symbol Description

This is an example of a temperature reading from
an external probe.

This is an example of a temperature reading from
the internal sensor.

This is an example of a minimum temperature,
which is the lowest probe temperature reading
from the day (CX402 models) or the lowest
ambient temperature reading (CX403 model)
within the current 24-hour period (midnight from
one day to midnight the next day) if the logger
was set to record logger checks (see Performing
Logger Checks). Otherwise the minimum and
maximum readings represent the entire logging
period and only reset when the logger is
downloaded and restarted or stopped and
reconfigured.

This is an example of a maximum temperature,
which is the highest probe temperature reading
from the day (CX402 models) or the lowest
ambient temperature reading (CX403 model)
within the current 24-hour period (midnight from
one day to midnight the next day) if the logger
was set to record logger checks (see Performing
Logger Checks). Otherwise the minimum and
maximum readings represent the entire logging
period and only reset when the logger is
