The VFC 400® Site Monitoring Kit measures and stores up to 15,905 temperature readings from an External Probe per device.
The loggers are designed to show ‘at a glance’ if temperature excursions have occurred during the current day and up to the previous 29 days. The display on each logger also show the current temperature reading, the current time, recording status and battery status.
The alarm is triggered if temperature readings are outside pre-set alarm limits. The status indicator changes from a check mark to an X and the audible alarm will sound.
From the display you can review the minimum and maximum temperatures for each day the VFC 400® has been logging up to 30 days.
The VFC 400® resets the min/max temperature at midnight every night and puts an inspection mark on the chart indicating the min/max has been checked.

The Site Monitoring Kit also comes with a docking station, so with one easy purchase you are ready to go with all your vaccine monitoring needs.

NOTE: Typical battery life assumes 6 minute logging, day statistics are reviewed on the display no more than once daily for no longer than 30 seconds each
time. Download data monthly.
NOTE: Continual activation of the audible alarm will reduce the working life of the battery. When an alarm is triggered, the alarm should be cleared and reset
as soon as possible.

Docking Station with USB Connection


LogTag's unique interface cradle design provides rapid and reliable data transfer to Control Solutions VTMC software in only a few seconds.


Control Solutions VTMC software provides chart production along with reporting.  Users can zoom in, annotate, and chart multiple units on the same graph.   Reports not only show how many alarms occurred, but how long the alarm occurred.


Software features Include
Automatic download of data when a new LogTag is inserted into an interface, with optional quick-reconfiguration using same parameters.  
Supports multiple interfaces thereby allowing multiple downloads and batch configuring of LogTags.
Display & printing of data in Chart, list or summary form.
Report Summary page with summary trip information.
Displaying multiple LogTag data on the same chart graph.
Saving downloaded LogTag data to file, retrieving previously filed LogTag data for review and email forwarding of data.
Automatic e-mailing to multiple recipients and automatic uploading of logger data to FTP sites for collation and review.
Support for Digital Signatures specifically in compliance to FDA 21 CFR Part 11 using optional Digital Signatures Support Suite.
Microsoft® WHQL Certified and digitally signed USB drivers.
Control Solutions VTMC is compatible with Windows 7 (32 & 64bit) or later



 The VFC 400 meets and exceeds all the CDC's recommendations for data loggers as listed below.  

CDC recommends thermometers with the following characteristics:
1. Provide continuous monitoring information with an active display.
2. Be a digital thermometer with a probe in a glycol-filled bottle.
3. Include an alarm for out- of- range temperatures.
4. Have a reset button if using a data logger with a min/max display.
5. Be capable of showing current temperature as well as minimum and maximum temperatures.
6. Be within +/-.5°C accuracy (+/°F).
7. Have a low battery indicator.
8. Store 4,000 readings
9.  User programmable logging interval
