Mean Kinetic Temperature (MKT)

Mean Kinetic Temperature (MKT) is a simplified way of expressing the overall effect of temperature fluctuations during the storage or transport of perishable products. MKT is widely used in the pharmaceutical industry as this parameter makes it possible to assess the effects of temperature changes on the quality of a vaccine and/or medicine.

MKT is calculated using the following formula:

Where:

$T_{K}\,\!$ , is the mean kinetic temperature

$\Delta H\,\!$ , is the activation energy

$R\,\!$ , is the gas constant

$T_{1}\,\!$ to $T_{n}\,\!$ , are the temperatures at each of the sample points

$t_{1}\,\!$ to $t_{n}\,\!$ , are time intervals at each of the sample points

In the ViGIE system, the sampling time is constant (typically 5 minutes) so the equation is simplified to:

Where:

$n\,\!$ , is the number of temperature sample points during the analysis timeframe

In the ViGIE system, MKT can be calculated automatically and consulted in the Sensor View, in the Analysis section and in the Monitoring Reports. Below is a representation of MKT in the Sensor View, for the selected timeframe.

To be able to see the MKT calculation for a particular sensor, you will need to ask the Support team to activate the calculation of this parameter. Please contact the ViGIE Support team using the contact details below.
