CX450 Temperature/Relative Humidity data logger provides highly accurate readings for critical pharmaceutical applications

Temperature Range: -30°C to 70°C (-22° to 158°F), Accuracy: ±0.5°C from -30° to 70°C, Resolution: 0.024°C at 25°C, NIST Calibration: Two-point NIST calibration included, RH Sensor Range: 0 to 95% (non-condensing)

Onset InTemp CX450 Temperature and Relative Humidity data loggerThe InTemp CX450 Temperature/RH data logger monitors temperature and relative humidity in storage and transportation environments. External sensor attached with the logger provides highly accurately temperature (-30C to 70C) and humidity (0% to 95%) readings.

CX450 Temp/RH logger with a built-in LCD display view temperature and relative humidity readings, visual alarms (and unique audible alarms), and battery level – plus the ability to view and display minimum and maximum readings, without affecting logged data.

It's 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.

With the use of InTemp CX5000 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. Learn more
