InTemp™ CX Temperature Logger (CX40x) Manual
19996-C
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 configurations designed for ambient storage, clinical refrigerator, freezer,
or refrigerator monitoring or you can set up a custom configuration for other applications. You
can also quickly perform daily logger checks, download reports, and monitor tripped alarms. Use
the built-in LCD screen to check the current temperature, daily maximum or minimum
temperatures, logging status, battery use, and more. 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.
