FAQs

Common Questions About Refrigerator Temperature Monitoring

Here are some common questions customers ask when selecting an environmental monitoring solution for refrigerators.

What temperature range should pharmaceutical refrigerators maintain?

Most pharmaceutical refrigerators must maintain a consistent temperature between +2 °C and +8 °C to meet industry regulations and protect product quality.

How many refrigerators can be monitored at once?

ELPRO solutions are scalable—from monitoring a single unit to an entire fleet across multiple facilities.

What types of alerts are available if a temperature excursion occurs?

Monitoring systems can trigger local visual/audible alarms or send real-time alerts via email and SMS to designated personnel.

Do the devices need to be wired, or are wireless options available?

ELPRO offers both wired and wireless monitoring solutions to accommodate different infrastructure needs and preferences.

Where is the monitoring data stored and accessed?

Depending on the setup, data can be stored locally on the device or uploaded to a centralized cloud platform for easy access and audit readiness.

How often should the sensors or loggers be calibrated?

ELPRO recommends calibration at least annually, in accordance with ISO standards, to ensure continued measurement accuracy.

Are ELPRO monitoring systems compliant with regulatory standards?

Yes, ELPRO devices and software comply with GxP requirements, FDA 21 CFR Part 11 and other global regulations.

What is the best way to monitor the temperature of a refrigerator?

The best way to monitor refrigerator temperature depends on regulatory requirements, risk level, and operational complexity. In regulated environments, manual checks are no longer sufficient.

  • Wired monitoring systems provide highly stable connections and are ideal for permanent installations or shielded rooms.
  • Wireless temperature data loggers offer flexible installation, faster deployment and minimal disruption—especially in active laboratories and clinics.
  • Cloud-based refrigerator monitoring systems enable remote monitoring, automated alerts, and centralized data access across locations.
  • Local (on-site) systems may be preferred where data residency or network restrictions apply.

For pharmaceutical and vaccine storage, a purpose-built refrigerator temperature data logger with calibrated sensors, long battery life, automated alarming and compliance features is considered best practice.

How do you record refrigerator temperature?

Recording refrigerator temperature using a temperature data logger involves:

  • Installing a calibrated temperature sensor or probe inside the refrigerator
  • Connecting the sensor to a refrigerator temperature monitoring device
  • Configuring alarm thresholds and alert recipients
  • Automatically recording temperature data at defined intervals
  • Reviewing data locally or via cloud-based software
  • Generating automated reports for compliance and audits

This automated process eliminates manual logging errors and supports continuous monitoring.
