Nextriv Track GPScold chain temperature logger

What it is for

The cold chain is an environment that destroys electronics: frost, condensation at every door opening, deep cold alternating with the warmth of the loading dock. Nextriv Track GPS does not pretend these conditions do not exist — it was engineered to live in them. The multi-layer sealed IP67 housing in food-grade plastic can lie directly next to food or medicines, withstands -35°C and condensation, and the batteries are swapped in a separate sealed compartment without exposing the electronics.

Its reporting philosophy fits in one sentence: routine data can wait — risk cannot. Normal readings are aggregated and sent in batches, stretching battery life into years; but a temperature threshold breach, a compartment opening (light sensor) or a tilt and shock (accelerometer) trigger an alert immediately. On top of that comes local memory for 5,000 records with retransmission: when the truck drives into a coverage "hole", the measurement history is not lost — it backfills itself once connectivity returns. For an auditor, that means a continuous, complete record of conditions from the warehouse to the recipient's dock.

It is the only device in the Nextriv sensor family that deliberately uses no gateways: it connects directly over the 4G cellular network (LTE Cat.1, its own micro-SIM card), so it works anywhere a truck can drive — with no infrastructure along the way. Each measurement is tagged with an approximate location derived from cellular base stations, and you can follow the shipment's current position live on a map in the Nextriv app — alongside the latest temperature and humidity readings. It is an indicative position (typical deviation on the order of 1 km) — enough to know where on the route the cargo is and prepare for its arrival, but not for precise navigation.

The measurement is of a class that refrigeration audits accept: typical accuracy of ±0.2°C in the range that matters most for refrigeration, and humidity accurate to about ±2% RH. Local logging and transmission are decoupled — data can be collected densely yet sent sparingly, reconciling documentation precision with years of battery life.

Usage scenarios

• Pharmaceutical transport: a pallet of vaccines travels 600 km under a +2…+8°C regime. A threshold breach generates an alert immediately — with the vehicle's approximate position — so the dispatcher can divert the truck to the nearest cold store before the batch is lost.
• Fresh and frozen food distribution: from the central warehouse to the store — every delivery carries a complete history of conditions. The "goods arrived thawed" dispute is settled by a chart, not one word against another.
• Container freight: the light sensor detects the container being opened away from its destination. Combined with the network position and timestamp, that is hard material for a claim or a theft report.
• Air freight: flight mode disables transmission for the duration of the flight in line with aviation requirements, while the device keeps logging measurements locally and backfills everything after landing.
• Medical and pharmacy refrigerators across a network of sites: the same logger watches medicine refrigerators in scattered clinics — it connects over the cellular network, so it needs no local infrastructure at all.
• Transport claims: the accelerometer records tilt and impacts — when cargo arrives damaged, the data shows on which leg and at what time the event occurred, cutting liability disputes short.

Key features

• IP67 sealing with multi-layer gaskets — resistant to condensation, frost and washdowns; built for cold-store reality, not just "indoor use".
• Food-grade ABS+PC housing — it can lie directly next to food and pharmaceuticals.
• A smart reporting strategy: routine readings aggregated (battery savings), risk events — temperature threshold, light, tilt — reported immediately.
• 5,000-record memory and automatic retransmission once coverage returns — a measurement history with no gaps, with log readout over NFC.
• 4G cellular connectivity (LTE Cat.1, its own micro-SIM card) — works along the entire route, with no gateways and no infrastructure of your own.
• Approximate network-based location from cellular base stations, reported alongside the measurements — shipment position visible live on a map in the Nextriv app.
• A 0–600 lx light sensor as a compartment- or crate-opening detector, plus a 3-axis accelerometer (tilt ±90°, shocks).
• Four mounting methods with no vehicle modification: cable ties, industrial tape, screws or a bracket.
• Flight mode with a schedule — compliant with air freight requirements.
• Replaceable batteries in a sealed compartment (~4.8–5.1 years of operation depending on the transmission mode) plus an internal USB-C port; activation via NFC, USB-C or a button.

In the Nextriv system

Measurements and positions flow into the Nextriv platform over the cellular network in near real time and land on the same dashboards as data from stationary sensors — warehouse and fleet in a single view. Temperature and humidity each take four thresholds (warning and critical min/max): a slight deviation produces a warning for the dispatcher, while leaving the regime raises a critical alarm distributed via e-mail, SMS, web push, MS Teams, Discord or an audible alarm in the app — and the webhooks integration forwards the event to the customer's TMS. Every event has a code, a status and comments — a ready-made trail for resolving matters with the carrier.

The complete route history — including data backfilled after coverage gaps — feeds PDF reports and XLSX/CSV exports that serve as documentation of transport conditions for quality procedures (e.g. HACCP) and settlements with recipients.

Typical deployments

• Pharma: continuous documentation of medicine transport conditions with an immediate alert on a regime breach — see solutions for pharma.
• Food and food service: a full temperature and humidity record from the warehouse to the point of serving — more in the solutions for food service.
• Cold stores and freezer rooms: supervision of chambers and transport in one platform, with compartment-opening detection — check the solutions for cold storage.
• Warehouses and 3PL: one logger covers storage and transport, with a consolidated report from the cargo's entire journey — details in the solutions for warehouses.
