WHO Approved Temperature Monitoring Devices for Storage & Transportation of Vaccine

Significance of Temperature Regulation in Vaccine Supply Chain

Vaccine are the biological product. It may get damaged due to temperature excursion & becomes ineffective to fight against the disease. Maintaining correct temperature during storage & transportation of vaccine is extremely crucial.

WHO Guidelines: Vaccines must be stored and transported between +2°C and +8°C throughout their journey.

Problem with Manual Monitoring: Traditional manual recording is time-consuming and prone to human error.

The traditional method of physically noting down the reading by shipping inspector is time consuming. This raise doubt about temperature monitoring efficiency & potency of vaccine. Involving high chance of human error. Our user friendly, compact & reliable WHO PQS Pre qualified Irreversible Freeze Indicator for continuous temperature monitoring is a solution. This gives assurance about potency of vaccine.

Solution – WHO PQS Devices:

• • LM Pro IN031 – WHO PQS certified under E006/IN03.1.
  • Compact, reliable, and user-friendly.
  • Provides irreversible freeze indication to confirm vaccine safety.

Complying with WHO PQS Norms

The World Health Organization has clearly defined the guideline for performance quality & safety (PQS) particularly in the context of the devices used for vaccine storage and transportation. G-Tek LM Pro IN031 abides with the WHO PQS guideline & is certified under WHO PQS E006/IN03.1

Product Detail

There are three models to choose from- Type A, Type B, Type C, based on the requirement of temperature and trigger time.

Freeze Indicator Models

• ✔ (Tick): Shipment remained above alarm limit.
• ✘ (Cross): Temperature fell below alarm limit beyond trigger time.
• Irreversible Alarm: Once triggered, cannot be reset—ensures audit integrity.
• Indicator “I”: Flashing symbol shows device is active.

All the parameters and alarm limits are pre-configured as per the requirement.

Benefits

• Compliance: Meets WHO PQS norms for vaccine storage & transport.
• Reliability: Irreversible alarms prevent tampering or misreporting.
• Audit-Ready: Provides clear proof of vaccine safety during inspections.
• Public Health Impact: Protects vaccine potency, ensuring effective immunization programs.

In Summary the irreversible freeze indicator is a single alarm electronic temperature indicator recommended by WHO are pivotal in upholding the quality and efficacy of vaccines. By ensuring that vaccines are stored and transported within the appropriate temperature range, these devices contribute to the success of immunization programs and the protection of public health.
