FAQs

Common Questions About Environmental Monitoring for ULT Freezers

Ultra low temperature (ULT) freezers, often storing sensitive materials at -80 °C or colder, require precise and reliable environmental monitoring to ensure compliance and protect valuable inventory. Below are common questions about ultra low freezer temperature monitors, sensors and data loggers.

 

What temperature range qualifies as ultra low and how precise should monitoring be?

Calibration frequency depends on internal SOPs and regulations, but annual calibration (every 12 months) with ISO 17025 certification is commonly recommended to ensure accurate temperature monitoring.

How often should sensors be calibrated for ULT monitoring?

Calibration frequency depends on regulatory requirements and internal SOPs, but a common standard is once every 12 months with ISO 17025 calibration.

Can ULT freezer alarms be customized for different thresholds or delays?

Yes, modern monitoring systems allow flexible alarm configuration, including alert thresholds, delays and escalation paths via email or SMS to reduce false alarms while ensuring rapid response.

Is it necessary to monitor both temperature and door openings?

Yes. Monitoring door openings alongside freezer temperature data provides critical context for excursions and helps identify handling patterns that may affect storage conditions.

What are the benefits of using cloud-based monitoring for ULT freezers?

Cloud-based systems offer 24/7 remote access, real-time alarming, audit trails and simplified compliance reporting—all key for centralized oversight and GxP compliance.

What are the benefits of ELPRO's ULT (ultra-low) data loggers for precise temperature monitoring at -80 °C?

Ultra low temperature freezer data loggers are specifically designed to deliver reliable, high-resolution temperature monitoring in extreme cold environments. These devices function as a critical sensor-based monitoring system for ULT freezers used in pharmaceutical, clinical and research laboratories. ELPRO's ULT data loggers provide:

  • Reliable recording of extremely low temperatures in ultra low temperature freezers
  • High measurement accuracy and long-term stability, even under cryogenic conditions
  • Flexible integration of ultra low temperature freezer data loggers into existing laboratory monitoring systems or cloud platforms
  • Secure temperature logging to support vaccine storage and long-term sample preservation

What are the key components of an ultra low temperature freezer monitoring system?

A complete monitoring system typically includes three core components:

  • Temperature sensors or probes (such as RTDs or thermocouples) designed for ultra low temperature ranges
  • A freezer data logger that records and stores temperature data continuously
  • Monitoring software that enables alarms, data visualization, reporting and compliance documentation

Can ultra low temperature monitoring systems support vaccine and clinical sample storage?

Yes. Ultra low freezer temperature monitoring systems are widely used for vaccine storage, clinical research, and biobanking, helping ensure temperature stability, data integrity, and regulatory compliance.
