Onset CX402-TxM Specifications

InTemp® CX402-TxM Data Logger

InTemp Bluetooth Low Energy Temperature (with Probe) Data Logger (CX402-TxM)

InTemp ® CX402-TXM (with Probe only) data loggers monitor
temperatures in refrigerators, freezers, and other temperature­controlled environments to comply with global GDP requirements.
The loggers communicate wirelessly via Bluetooth Low Energy to
mobile devices. Using the InTemp app, you can easily view data,
check logger status, set alarms, and create and share secure PDF
reports for streamlined reporting and regulatory compliance. All
loggers feature a built-in LCD display to view current and daily min
and max temperatures, advanced audible and visual alarm
capabilities for notification of temperature excursions, an internal
sensor for ambient temperature monitoring, and a single-point NIST
Certification of Calibration for both the logger body and probe.

With the optional CX Gateway, you can get remote notifications of
temperature excursions and automatically download data from
loggers within range of the device. Learn more about the CX
Gateway here.

Models are available with a 2- or 4-meter external temperature
probe for tracking actual refrigerator temperatures without Glycol
buffers or freezer applications.
