Protecting inventory, life,
and equipment.
Safeguarding valuable stock is the first priority whether in pharma, biotech, food processing, or logistics. Thermologie reduces the risk of inventory loss with accurate, automated monitoring and real-time alerts.
But it goes further. With Thermologie's unique AI-assisted oversight, subtle anomalies - that would never be noticed by a human - are monitored and analyzed. This way, small equipment failures can be identified early, long before they escalate into costly or catastrophic failures.
Thermologie Cloud
Every W2 logger connects automatically to the Thermologie Cloud. Data is securely logged, timestamped, and synced in real time — available anywhere, on any device. Alerts are delivered the moment something requires attention.
From a single fridge to a global supply chain, the Thermologie Cloud gives you oversight that scales with your operation, always and anywhere accessible.
Secure
Enterprise-grade security with encrypted communication, verified devices, and MFA.
All in one Place
Monitoring, Logging, Alerts, Reports, and Calibration data - organized & trusted.
Access from Anywhere
Always, instantly available - on your phone, tablet, or computer.
Scaleable
Made to grow with you: from small teams to multi-site enterprises.
Compliance Built-in.
Compliance is at the core of Thermologie. Both the W2 and the Cloud platform are designed around global standards and regulatory requirements, ready for use across pharma, biotech, food, storage, and logistics.
Apart from the unmatched monitoring & alerting features, every reading is captured, timestamped, and preserved. Calibration certificates are linked directly to each device, logs sync automatically and securely to the cloud, and reports are audit-ready in a single click.
Everything you need is in one place — organized, traceable, and always available. Inspections become routine instead of stressful, and staying compliant no longer drains time and energy.
Global Standards
Designed for EN12830, HACCP, GxP, and ISO workflows.
Automated Logging
Every log is timestamped and stored securely.
Instant Reports
Audit-ready compliance reports are generated in a single click, ready for inspections.
Tamper-Proof Records
Logs protected against modification or loss.
Clear idea of what’s going on.
And what may be going on.
The best data is data you don’t have to think about.
We put a lot of care into data visualization to be intuitive and instantly readable. It feels natural, like a language you already know - no effort, no confusion, just clarity when you need it.
Thermologie AI: It notices what others miss.
Thermologie’s AI system detects subtle anomalies invisible to the human eye, predicting potential equipment failures. These early warnings let you fix issues while they’re still simple and inexpensive, before they escalate into costly breakdowns.
