Atlas Log-TH Temperature Humidity Data Logger
A reusable external-probe logger for dry ice, ultra-low freezers and specialist cold-chain applications. It combines real-time LCD status, configurable alarms, temporary reporting and automatic PDF/CSV output.
Introduction
The Atlas Log-TH Temperature Humidity Data Logger is a configurable USB monitoring device designed to record both temperature and relative humidity during transportation, storage and laboratory operations. Its external probe can be positioned inside refrigerators, medical cold boxes, cabinets, containers and controlled chambers while the LCD display and controls remain easy to access.
The logger supports single-use or multi-use operation and can be prepared before deployment with Freshliance Tools. Users can configure the logging interval, start delay, temperature and humidity alarm limits, report options and other operating parameters. The LCD provides real-time readings together with battery level, alarm status, maximum, minimum and average information.
After the monitoring period, the device connects directly to a computer through USB and automatically generates PDF, CSV or combined PDF-and-CSV reports. Temporary report and pause functions support inspections during an active monitoring assignment without losing the complete recorded history.
Key Features and Benefits
Temperature and humidity monitoring
Records both environmental measurements for sensitive products and controlled facilities.

Freshliance Tools-ETH
Freshliance Tools-ETH is desktop software designed for use with the Atlas Log-TH Temperature and Humidity Data Logger. It provides three main working areas: Summary, Graph and History.
On the Summary page, the software automatically identifies the connected logger and displays its device ID, model, recording type, sensor type, battery level, operating status and other device information. Users can then configure the logger according to the application, including start mode, start delay, time zone, time format, logging interval, report format, PDF or software password, and high and low alarm limits.
During or after recording, users can reconnect the device to review statistical information. The Graph page provides a clear time-versus-temperature and humidity chart that can be saved as a PNG file. It also displays the complete recorded data list and summary, with export options for PDF, CSV and TXT reports.
The History page keeps a record of devices previously read by the software, making it easier to manage repeated monitoring activities and retrieve earlier logger information.
Automatic device recognition
Identifies the logger model, device ID, sensor type, battery level and operating status as soon as it is connected.
Complete configuration
Set start mode, delay, time zone, logging interval, report format, passwords and alarm thresholds.
Graph and data analysis
Review time-based temperature and humidity graphs, recorded data and statistical summaries.
Flexible report export
Save graphs as PNG files and export monitoring reports in PDF, CSV and TXT formats.
