Temperature Data Logger "HOBO " Model CX405 RTD Dry Ice Data Logger

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. The logger uses Bluetooth Low Energy (BLE) technology to wirelessly communicate with the InTemp CX5000 Gateway and/or the free InTemp mobile app and send data to the free InTempConnect cloud platform. The CX405-RTD has a built-in 1.5 m external probe that can measure temperatures as low as -95°C (-139°F) and up to 50°C (122°F) with a high degree of accuracy. The device also has a protective sheath to prevent accidental cutting of the probe cable and includes a clip for secure mounting.

The CX405 Dry Ice data logger also features a built-in LCD display to view temperature readings, visual alarms (and audible alarms), and battery level – plus the ability to view and display the minimum and maximum readings.

With the addition of the InTemp CX5000 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.
