Without Temperature Monitoring Devices

Temperature excursions go undetected

Without a product-level indicator, breaches during transit, storage or handling are invisible until damage is already done.

Compliance demands evidence

Life Science, Food safety, pharmaceutical, Technology and logistics regulations require proof that conditions were maintained throughout the supply chain.

Product losses are costly

Spoiled /pharmaceuticals, rejected food shipments and compromised biologicals, chemicals represent significant financial and reputational risk for any business.

One platform. Limitless indicators. The right tool for every application.

All Holtronic neo®  indicators share the same core platform technology: designed in the UK, built for precision, and optimised for real-world supply chain and storage conditions.

🚨

Irreversible breach records

Once a threshold is exceeded, the indicator displays it permanently. Evidence cannot be obscured, reset or manipulated.

📈

Audit-ready reports

neo®  Blu generates downloadable reports detailing breach extent, duration and timing — ready for quality control and regulatory audit systems.

🔎

Product-level traceability

Each indicator travels with the individual product — providing granular, item-level condition data that system-level loggers cannot offer.

Activation

Press to start. That's it.

Holtronic indicators are activated with a single button press. Once started, the indicator begins logging immediately — no pairing, no configuration, no software setup required at the point of deployment.
This simplicity is by design. Whether you’re activating hundreds of units in a production environment or a single indicator in a hospital cold room, the process is identical and instant.

UK-engineered for reliability in demanding environments

Immediate monitoring from the moment of activation

Designed for deployment at scale

Wherever product integrity matters

Holtronic indicators are deployed across industries where temperature control is not optional — it’s a matter of safety, compliance and commercial integrity.

💊 Pharmaceuticals & Vaccines

Maintain drug efficacy and vaccine viability across distribution, storage and last-mile delivery. Critical for 2–8°C cold chain and biologic stability.

🥩 Food Safety & Distribution

Protect perishable goods from farm to shelf. Demonstrate HACCP compliance and prevent spoilage across chilled and frozen logistics.

🚚 Logistics & Cold Chain

Monitor temperature conditions across vehicles, warehouses and distribution hubs with product-level evidence at every transfer point.

⚗️ Industrial Chemicals

Protect the integrity of temperature-sensitive chemicals in storage and transit. Prevent degradation, hazardous reactions and regulatory non-compliance.

🔬 Life Sciences & Research

Ensure biological samples, reagents and test kits are maintained within precise temperature windows throughout handling and storage.

🏭 Consumer Goods & Manufacturing

Protect high-value manufactured goods with temperature-sensitive components from production through to consumer delivery.
