The Atlas Log-90 Multi-use Ultra Low Temperature Data Logger is a device with an external probe that can measure ultra-low temperature ambient temperatures. It can accurately measure as low as -90°C (-130°F) and up to 200°C ( 392.0 °F) temperature. Designed to handle extreme cold environments, it ensures the integrity of stored materials such as biological samples, vaccines, and sensitive chemicals, helping to maintain their quality and viability.

Atlas Log-90 Multi-use Ultra Low Temperature Data Logger has an LCD display through which you can view the real-time, maximum/minimum/average temperature values of the device, as well as alarm and operating status and battery power, which can remind the user to pay attention to the environment in a timely manner Make adjustments to the temperature. After the trip, you can use the USB plug to connect to your computer to generate PDF/CSV/PDF+CSV reports with charts and tables, without the need for additional software.


Parameters configurable
Parameters can be configured freely through configuration software.

Replaceable battery
Its battery lasts up to 90 days. Batteries can be replaced and reused.

Alarm points and markers
Up to 6 alarm points can be set and up to 9 marks can be made.

password protection
