The InTemp ® CX403 data logger features an internal sensor for monitoring ambient temperature. The logger communicates wirelessly via Bluetooth Low Energy to mobile devices. The CX403 features a built-in LCD display to view ambient temperature, advanced audible and visual alarm capabilities for notification of temperature excursions, and a NIST Certification of Calibration.
With the optional CX Gateway, you can get remote notifications of temperature excursions and automatically download data from loggers within range of the device. Learn more about the CX Gateway here.
