InTemp Temp/Relative Humidity Data Logger

$159.00 USD

Important Information

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


The InTemp CX450 Temp/RH data logger monitors temperature and relative humidity in storage and transportation environments. It uses Bluetooth technology to wirelessly communicate with the InTemp CX Gateway and/or the free InTemp mobile app, and sends data to the free InTempConnect cloud platform. The external sensor provides highly accurately temperature (-30C to 70C) and humidity (0% to 95%) readings.

This Temp/RH logger also features a built-in LCD display to view temperature and relative humidity readings, visual and unique audible alarms, and battery level. Users can also view and display minimum and maximum readings, without affecting logged data.

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