Simple shipment checks
Small indicator. Clear temperature status.
A compact, single-use electronic temperature indicator for checking the status of temperature-sensitive consignments, with three LEDs and simple break-off activation.
The Tempmate®-i1 travels with your goods and indicates whether configured temperature limits have been breached. Its slim, lightweight format fits alongside the consignment, while the onboard LEDs let the receiving team check the status without connecting a reader or opening software.
Choose the configuration around your shipment requirements. The measuring range describes the device’s capability; the selected alarm limits define the conditions it checks during the journey.
