AlertTag T20 Single-use Temperature Indicator with LCD Display is highly accurate. With the compact and highly reliable design, the electronics temperature indicators can measure the transportation environment of temperature-sensitive products. The user-friendly and intuitive display can show the alarm state clearly. Up to 4 different alarm points can be programmed to customer requirements. This indicator applies to the pharmaceutical industry, including vaccines, protein, or any temperature-sensitive product shipment monitoring.


Easy-to-read screen display

The user-friendly LCD screen can view the Max. and Min. temperature, current temperature value, and alarm status enabling immediate and easy decision-making.

Four alarm points are available

Up to 4 alarm settings - two groups of high and low alarms. When the temperature exceeds the preset value, the corresponding alarm point 1, 2, 3, or 4 will be displayed.

Reliable electronic design with high accuracy

Built-in Japan-made smart thermometer sensor, with a measuring accuracy of ±0.5℃ at full range (-30℃ to +70℃). Up to 3 years working time , with a shelf life of 2 years.

Compact design and easy to place

The compact design with the plastic shell is more suitable for medical transportation. The Electronics Indicators can be directly stuck on the product package to monitor the temperature.

AlertTag T20 LCD Sing-use Temperature Indicator is a temperature indicator for blood, 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 temperature changes during the transportation of biologics.

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