Atlas Log Series are Single use/Multi use, configurable, battery-replaceable temperature loggers with external probes featuring high-resolution temperature ranges of -196℃ to +200℃. Atlas Log Temperature Data Logger is equipped with LCD screen, which can view real-time temperature data. Its capacity reaches Max. 35000 readings. Professional users can use the configuration software to configure parameters, and after completing the trip, an encrypted report can be automatically generated. Temporary mode allows the device to continue working after the user generates and reads a temporary report. This temperature data logger is designed for cold chain logistics, storage and transportation. It is an ideal solution for ultra-low temperature transportation and temperature monitoring that requires frequent temperature recording.


Parameters configurable 

Parameters can be freely configured through the configuration software.

Replaceable battery

The battery can be replaced.

Alarm points and markers

Up to 6 alarm points can be set, and up to 9 markings can be made.

Password protection

Password can be set to prevent others from operating the equipment without authorization.

High precision 

The external probe can measure temperature as low as -196℃ with high accuracy.

Intuitive LCD display

LCD displays all parameters: normal, alarm, max/min/average temperature value, running status, and battery level.

Temporary Report Available

Temporary mode allows the device to continue working after the user exports and reads a temporary report. Current data information can be read via configuration software.

Automatic PDF/CSV Reports

It can automatically generate PDF/CSV/PDF+CSV reports with graphs and tables without additional software.

LCD alarm indication 

Once the temperature out of the presetting alarm range, the alarm symbol(x) will be displayed on the LCD screen


Temperature units switchable

Celsius (℃) and Fahrenheit (℉) can be freely switched.

Atlas Log Series are Single use/Multi use temperature loggers with LCD screens and external probes featuring high-resolution temperature ranges of -30℃to +70℃, -90℃ to +200℃, and -196℃ to +90℃. It is an ideal choice for ultra-low temperature transportation and temperature monitoring solutions requiring frequent temperature recording. It is used to record and monitor the ultra-low temperatures in cold storage, cold chain transportation, and dry ice storage environment.  

Biological products such as vaccine reagents are extremely temperature-sensitive and temperature changes during storage and transportation should be monitored and controlled in time. The Atlas Log temperature data logger with a real-time temperature display is ideal for the pharmaceutical industry and biological products. It can be used for continuous recording of biopharmaceuticals, life sciences, biological samples, pharmaceutical cold chain, vaccine cold chain, blood cold chain, and diagnostic reagents (including biological reagents, molecular reagents, covid-19 reagents, and cell biology reagents) in a low-temperature environment.


Freshliance Tools

Freshliance Tools is a desktop software for users to use Freshliance USB data loggers. It consists of three pages: Summary, Graph and History. On the Summary page, the software will first automatically identify ID, model, recording type, sensor type, battery level, status and other information of the device plugged in. And then users can configure the data logger as needed, including start mode, start delay, time zone, time format, logging interval, report format, PDF/software password, high and low alarm, etc. During or after data recording, user can also check statistical information of the device after plugging it in. Besides, the graph page provides a simple X–Y plot of time versus temperature/humidity which can be save as PNG format file, a list and a summary of all data recorded, as well as an option to export the report in PDF, CSV, TXT format; and the history page provides a list of all the devices whose report was read by this software.

The software is designed for Fresh Tag 10T/TH, Thermis Log 10T/TH, Tagplus-T/TH, Atlas Log-30/60/90/200/IUT, Rugged data logger, Keeper 1/IUT, COEUS-UEX.
