Ultra-Low Freezer Monitoring
Cold Storage & Deep Freezers
Continuous monitoring for –80°C ultra-low temperature freezers. High-accuracy PT-1000 probe sensors deliver precise readings while redundant alerting with multi-tier escalation workflows ensures rapid response to any deviation that could compromise stored biological materials.
Ultra-Low Freezer Sample Protection
Biological materials stored at –80°C are irreplaceable, and even a brief temperature excursion can destroy entire sample collections worth years of research. This offering ensures that any deviation from the validated storage range triggers an immediate, escalating alert chain so that responsible personnel can intervene before sample integrity is compromised.
How it's deployed
PT-1000 probe sensors rated for –80°C are installed directly in the freezer chamber and connected to a dedicated gateway that transmits readings at configurable intervals. Multi-tier escalation workflows route alerts first by SMS and email, then by voice call if no acknowledgment is received within a defined window, eliminating silent alarm failures.
Evidence & Reporting
The system generates continuous EN12830-compliant temperature logs with tamper-evident audit trails that satisfy GDP and GMP documentation requirements. FDA 21 CFR Part 11 electronic records are supported, including user authentication, electronic signatures, and a full change log for every configuration adjustment.

Frequently Asked Questions
The logger stores readings locally and transmits them once connectivity is restored, ensuring no data gaps in the audit trail. Separately, the multi-tier voice call escalation continues independently of cloud connectivity so on-call staff are still reached.
PT-1000 resistance-temperature detectors maintain ±0.3°C accuracy across the full –80°C range, whereas NTC thermistors can drift significantly below –40°C. This level of accuracy is required to demonstrate meaningful compliance with GMP temperature band specifications.
Yes, each monitored unit has its own independently configured high and low threshold set, delay time before alert, and escalation contact list. This lets you apply tighter limits on archival sample freezers while using wider bands for short-term working stock.
