Smarter Electronic Temperature Monitoring

The Holtronic neo® Blu is a wireless electronic temperature data logger that transfers complete breach records — including extent, duration and timing — contactlessly to any Android device. No cables. No internet. No physical access to the device needed.

The Holtronic neo® Multi is the first electronic temperature and time indicator you can reset and reuse — up to 90 times per unit. Purpose-built for return-to-base cold chains, it delivers the same precision breach monitoring as a single-use device, at a fraction of the long-term cost.

The Holtronic neo® TTI is an electronic time-temperature integrator that calculates the cumulative thermal load experienced by your product, not just whether a threshold was breached, but what that means for remaining shelf life. Purpose-built for pharmaceutical cold chain, with dedicated 2–8°C configurations for vaccines, biologics and refrigerated medicines.

The Holtronic neo® Penta is a compact, single-use electronic temperature alarm indicator with up to five programmable LED threshold alerts. At just 6g, with ±0.5°C accuracy, irreversible tamper-proof breach records and a 2-year shelf life, it is the complete single-use cold chain monitoring solution for pharmaceuticals, food safety and logistics.

Integrate Holtronic neo® electronic indicators directly into your packaging, from primary blister packs to insulated shippers, and transform every unit you send into a self-monitoring, self-documenting smart package with visible LED alerts and wireless data transfer.
