InTemp CX405 RTD Dry Ice Data Logger

$240.00 USD

Important Information

For automatic downloads and remote alerts, InTemp loggers require the optional InTemp CX Gateway. MORE INFORMATION


The InTemp CX405-RTD Dry Ice data logger is specifically designed for ultra-low temperature monitoring of vaccines and pharmaceuticals in storage and transportation environments. Using Bluetooth technology, it wirelessly communicates with the InTemp CX Gateway and/or the free InTemp mobile app, which send data to the free InTempConnect cloud platform. Its built-in 1.5 m external probe can measure temperatures as low as -95°C (-139°F) and up to 50°C (122°F) with a high degree of accuracy, and a protective sheath prevents accidental cutting of the probe cable. Includes a clip for secure mounting.

This dry ice data logger also features a built-in LCD display to view temperature readings, visual and audible alarms, and battery level – plus the ability to view and display the minimum and maximum readings.

By adding the InTemp Gateway, users can get text or email notifications of temperature excursions, as well as automatic data downloads from loggers within range of the CX Gateway device.
