LM Pro IN031
It is very critical to know and ensure that a lifesaving drug like vaccine is stored according to the recommended temperature throughout its lifecycle. WHO PQS E06/IN03.1 clearly defines the requirements for monitoring of vaccine temperatures during the different phase of vaccine cold chain. LM Pro IN031 is an Irreversible Freeze Indicator. There are three models to choose from- Type A, Type B, Type C, based on the requirement of temperature and trigger time.
A clearly visible “✔” indicates temperature is above freezing temperature and “X” indicates whether temperature has dropped below the pre-configured alarm limits as per the WHO PQS guidelines. It comes with an NABL traceable calibration certificate.

FAQs
LM Pro IN031
The G-Tek LM Pro IN031 is a WHO-approved irreversible freeze indicator. It helps ensure vaccines and other temperature-sensitive products stay within safe limits during storage and transport.
A Checkmark (✔) on the display means the product is within the safe temperature range.
A Crossmark (X) indicates that the temperature has dropped below the pre-set freezing threshold.
The LM Pro IN031 is WHO PQS Certified (E006/IN03.1) and meets global standards for vaccine freeze monitoring.
Press and hold the activation button for at least 10 seconds until the LCD lights up showing a checkmark (✔) and a blinking dot on the right side.
No, it’s a single-use device designed for irreversible freeze indication.
