MadgeTech’s Vaccine Temperature Monitoring System (VTMS) is ideal for the continuous measure- ment and data logging of temperature sensitive vaccines or pharmaceuticals in refrigerators, freezers, and coolers. The system includes an NIST traceable RFTCTemp2000A data logger with thermocouple and Glycol bottle. Additionally, the RFTCTemp2000A data logger in the VTMS system has a convenient LCD to ensure temperature parameters are met, in real time. Starting, stopping and downloading from the device are all performed wirelessly using the RFC1000 wireless transceiver. The current reading, minimum, maximum and average statistics can all be obtained through the display.
The convenient digital display provides the current reading for the thermocouple channel. Minimum, maximum and average statistics are also provided for a convenient snap shot of the logged data. For instant, out of range notification, an audible buzzer as well as LED alarm indicator notifies users when the temperature is above or below the user specified alarm. The RFTCTemp2000A also features programmable trigger settings for applications in which temperature logging is critical only above or below a certain temperature.
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 utilizes the new MadgeTech 4.0 Software. Data can be viewed in graphical or tabular formats and summary and statistics views are available for further analysis. The software features export to Excel®, data annotation, digital calibration and more.
