  • Assurance at a Glance

    InTemp CX400 series loggers feature a large LCD display to make it easy to keep tabs on current and daily min and max temperatures throughout the day. Everything is displayed at once – so there’s no need to toggle your way through a series of screens.

    The LCD also makes your life easier by displaying checkboxes when daily temperature checks are done, a visual alarm indicator if an excursion occurs, and ambient temperature readings.

  • Low Power, High Performance

    Because InTemp loggers require very little power to operate, they can monitor temperatures for up to a year without changing the batteries. And, when they finally do wear down, you can replace them yourself with two AAA batteries.

    Battery power also reduces the risk of temperature data loss during power outages.

  • Second Sensor Built In

    InTemp loggers come with a second, built-in temperature sensor to track ambient temperatures. This eliminates having to buy a separate room temperature logger, and can provide useful information about room conditions during an excursion event.

  • The Ultimate Logger

    CX400 loggers combine the right set of features to optimize your process and make you more efficient.

An App for Your Process

The free InTemp app makes it a snap to configure and read out InTemp loggers. View data, check logger status, set alarms, and create and share secure PDF reports to streamline reporting and compliance.

Data You Can Trust

InTemp data loggers have an accuracy of +/-0.5°C and come with a NIST Certificate of Calibration. Advanced certificates of calibration come standard for VFC loggers requiring an ISO 17025 compliant certificate.


InTemp iPad App

In the Know

InTemp loggers provide alarms to keep you notified of excursions or if the temperature sensor becomes detached. When an alarm trips, an LED on the logger's screen begins blinking, an alarm icon appears on the logger and in the InTemp app, and the logger starts beeping every 15 seconds until corrective action is taken. And, when used in conjunction with the InTemp Gateway app and InTempConnect, you can get real-time alert notifications of excursions on your mobile device.
