Overview of the InTemp CX703 Cryogenic Temperature Data Logger
The Onset InTemp CX703 is a low-cost wireless temperature data logger designed for cryogenic applications. Utilizing a Bluetooth Low Energy (BLE) connection the logger can transmit recorded data to any mobile device running the InTemp app. The CX703 can record temperature data for up to 365 days and can monitor temperatures as low as -200°C (-328°F) with its 1.5-meter external probe. Logger configuration and data download is done through the free InTemp app which offers multiple preset configurations, as well as the ability to create custom configurations. Red and green LEDs quickly tell you if temperatures have stayed within range or not. Once downloaded the data can easily and quickly be analyzed from within the InTemp app as well as exported as needed.
When used with the optional CX Gateway (sold separately) you can receive real-time notifications of temperature excursions we well as automatic downloads of data from loggers within the range of the device.
