LogTag TIC20 WHO Approved Vaccine Indicator


The LogTag® TIC20 is a versatile, wide range, multi-trip Temperature Indicator, featuring high resolution temperature readings over a measurement range of -40°C to +85°C (-40°F to +185°F). Enclosed in a robust and durable polycarbonate case, the TIC20 features a real time clock, which provides date/time stamps for each temperature reading.

Using the LogTag® Interface and the freely available companion software LogTag Analyzer, the LogTag® is easily set-up for recording conditions including delayed start, sampling interval, number of readings, continuous or fixed number of readings and configuration of conditions to activate the ALERT indicator. Readings are downloaded using LogTag® Analyzer, which provides facilities for charting, zooming, listing data statistics and allows exporting the data to other applications such as Excel.

The LogTag® TIC20 complies with the relevant international standards for temperature monitoring devices, such as FCC, CE, C-TICK, and RoHS. This not only demonstrates the quality of the LogTag® TIC20, but underlines its suitability for temperature monitoring applications where accuracy and consistency is required.
