Suitable for affixing to packages, cases or pallets, the TempTRIP one-touch, UHF radio identification temperature tag has a tactile button that is pressed to start and/or mark temperature data at multiple points throughout a product’s cold chain journey. If the temperature is out of range, an LED light on the tag blinks red when the button is pressed; it displays a solid green if programmed parameters have been met. Custom product configurations can be written to the tag and updated in the field. The tag’s microprocessor allows a variety of calculations, including remaining shelf life, mean kinetic temperature and multi-parameter alarms. The tag has a temperature range of -30°C to 55°C with accuracy of +/-0.2°.
