The neo® Penta is a compact, single-use electronic temperature indicator built to flag up to five distinct temperature events on one device. It starts recording the moment it’s activated, samples continuously throughout the journey, and lights an irreversible LED the instant any defined threshold is crossed. A permanent, tamper-evident record of temperature abuse that travels with the product from dispatch to delivery.

The neo® Multi is Holtronic’s patented, resettable electronic indicator. It monitors temperature continuously throughout a journey, flags a breach the moment your defined limit is crossed, and resets in seconds using the dedicated Holtronic reset unit — ready to go straight back into service.

The neo® Blu is Holtronic’s Bluetooth-enabled single-use temperature data logger. It combines on-device LED breach alerts with wireless data retrieval — pull a complete temperature history from the indicator to your phone without opening the package, unplugging a cable, or touching the device. One button press to start. One app to read the record.
