Ultra-Low Freezer Temperature Monitoring System

What’s stored at -80°C usually can’t be replaced. PharmaWatch monitors every ultra-low freezer continuously — catching equipment degradation, temperature drift, and power failures before your samples pay the price.

Real-Time Alerts & Predictive Equipment Failures
PharmaWatch doesn't wait for temperatures to drift. It reads the early warning signs — compressor cycle frequency, recovery duration, performance trends — and alerts you weeks ahead of failure.

Automated Compliance Records
Every reading logged automatically with a timestamp. Every alarm documented with a user ID and resolution note. GLP, GxP, CAP, and FDA 21 CFR Part 11-compliant records — built continuously, no manual entry required.

Up and Running in Minutes
Ships pre-configured. Plug it in and monitoring starts immediately — no IT, no WiFi, no setup. Most facilities are live the same day their equipment arrives.

Frequently ask a questions

What temperature ranges does PharmaWatch monitor for ultra-low freezers?
PharmaWatch monitors from -40°C to -80°C and below — covering standard -80°C biospecimen and cell therapy freezers, mRNA and ultra-cold vaccine storage (-60°C to -80°C), and long-term sample archive units.
How does PharmaWatch detect when a ULT freezer is starting to fail?
PharmaWatch tracks compressor recovery times and cycle patterns continuously. As a compressor degrades, recovery times lengthen and cycles become more frequent — often weeks before temperatures are affected. You get an alert in time to act before any samples are at risk.
Why does it matter that there are no physical buffers in the freezer?
Glycol buffers and glass beads introduce contamination risk in ULT environments storing cell therapies or irreplaceable biospecimens. PharmaWatch’s patented VTB™ models actual product temperature algorithmically — nothing physical inside your freezer, no contamination risk.
What happens if the power goes out?
Built-in 5-day battery backup keeps monitoring running independently of your power grid. Your team is alerted immediately via call, text, or email. When power returns, all timestamped data syncs automatically. Zero gaps in your compliance record.
Does PharmaWatch work without WiFi?
Yes — entirely on cellular. No network credentials, no firewall changes, no IT involvement. Monitoring keeps running during WiFi outages, IT maintenance, and power interruptions.
What compliance standards does PharmaWatch support for ULT freezer monitoring?
FDA 21 CFR Part 11, FDA GxP and GLP, CAP, CLIA, FDA HCT/Ps and CGTP, and AABB. IQ/OQ/PQ validation documentation included in every deployment at no additional cost.
How does calibration work for ULT sensors?
ISO 17025 pre-calibrated replaceable probes with a 2-year calibration interval. Replacement probes ship automatically before expiration — swap in seconds, monitoring stays continuous. NIST-traceable certificates permanently linked to each device record.
Can PharmaWatch monitor multiple ULT freezers across different buildings?
Yes. Multi-building and multi-campus deployments from one centralized dashboard. Real-time status and compliance reports for any asset in 3 clicks, from any device, anywhere.
