InTemp ® CX402-TXM (with Probe only) data loggers monitor temperatures in refrigerators, freezers, and other temperature-controlled 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.
Models are available with a 2- or 4-meter external temperature probe for tracking actual refrigerator temperatures without Glycol buffers or freezer applications.
Highlighted Features:
Easy-to-read display with current and daily min/max temperatures
Bluetooth transmission of data and alarm states
Logger setup and download of data in seconds – without a PC or cable
Real-time alerts and automatic data downloads with optional CX Gateway device
+/- 0.5C accuracy for reliable temperature readings
Battery-powered to guard against local power loss
