Options for this product


InTemp CX402-Txxx (with Glycol Bottle) data loggers monitor temperatures in refrigerators, freezers and other temperature-controlled environments to comply with global GDP requirements. The loggers communicate wirelessly via Bluetooth to mobile devices. Using the InTemp app, you can easily view data, check logger status, set alarms, and create and share secure PDF reports for streamlined reporting and regulatory compliance. All loggers feature a built-in LCD display to view current and daily min and max temperatures, advanced audible and visual alarm capabilities for notification of temperature excursions, an internal sensor for ambient temperature monitoring, and a single-point NIST Certification of Calibration for both the logger body and probe.

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.

Models are available with a 2- or 4-meter external temperature probe attached to a Glycol bottle used to insulate the probe and delay thermal response times.


  • Integrates with mobile and cloud platforms for a 21 CFR Part 11 compliant solution
  • Easy-to-read display with current and daily min/max temperatures
  • Bluetooth transmission of data and alarm states
  • Logger setup and download of data in seconds – without a PC or cable
  • Real-time alerts and automatic data downloads with optional CX Gateway device
  • +/- 0.5C accuracy for reliable temperature readings
  • Battery-powered to guard against local power loss
  • Several Glycol bottle/probe-only options available
  • Includes 1-year NIST calibration, per USP guidelines


Who is this for?

The InTemp CX402-Txxx data logger (with probe in glycol) is right for you if:

  • You work for an organization that’s required to primarily follow GDP/GMP, FDA, USP, and/or EU/CE guidelines for monitoring ambient to frozen temperatures
  • Your organization is a pharmaceutical manufacturer, third-party logistics company, Life Science/Biotech storage and transportation company, or other organization looking to monitor temperature-sensitive goods
  • You need a 1-Year NIST-certified data logger (probe and ambient temperature sensor), as recommended by the previously mentioned regulatory bodies

Required to follow GDP & GMP requirements, specifically:

  • Probe in glycol
  • GDP/GMP compliant
  • Frozen to ambient monitoring
