AlertTag T20 LCD Disposable Temperature Monitor/Indicator is a Temperature Indicator for vaccine, bio-pharmaceuticals, life sciences, biological samples, blood cold chain transportation, diagnostic reagents, including biological reagents, molecular reagents, COVID-19 reagents and cell biology agents. 

While common drugs are inorganic molecules, biologics are all active molecules. The organic components in biologics are temperature sensitive because of biological activity. So there is a need for our time temperature indicator to monitor the change of temperature in the transportation of biologics.

Products such as biologics and vaccines have a short shelf life, so the temperature change during transportation should be controlled in time. Our cost-effective, easy-to-operate Electronics Temperature Indicators with real-time temperature display are ideal for the pharmaceutical industry and biologics.
