MadgeTechs Vaccine Temperature Monitoring System (VTMS) is ideal for the continuous measurement and data logging of temperature sensitive vaccines or pharmaceuticals in refrigerators, freezers, and coolers. The system includes a NIST traceable RFTCTemp2000A data logger with thermocouple, Glycol bottle and a power supply. Additionally, the RFTCTemp2000A data logger in the VTMS system has a convenient LCD to ensure temperature parameters are met, in real time. The current reading, minimum, maximum and average statistics can all be obtained through the display.

In the real-time chart recording mode the VTMS can alert the user, or other personnel, via e-mail or text message if the refrigerator has failed, or if the temperature is outside of the nominal range. This allows users to take immediate actions to ensure vaccines and pharmaceuticals in storage are not destroyed. To prevent false alarms, the RFTCTemp2000A is connected to a Glycol bottle which provides temperature buffered readings.

The VTMS is available with an extended warranty.
