Temperature Excursions
Readings drift outside safe ranges without anyone noticing until the shipment has already been affected.
COLD CHAIN INTELLIGENCE
Real-Time Cold Chain Monitoring for Every Shipment
Protect temperature-sensitive products across refrigerated trucks, containers, warehouses and last-mile delivery with connected sensors, GPS visibility, instant alerts and compliance-ready reporting.
Product Overview
One Connected View of Every Cold Shipment
PolarGrid Cold Chain Monitoring connects temperature sensors, humidity sensors, door sensors, GPS trackers and IoT gateways to a single cloud dashboard, giving operations, quality and compliance teams a live, shared view of every refrigerated asset.
The solution is built to support refrigerated trucks, reefer containers and cold rooms, along with pharma logistics, frozen foods, dairy distribution, seafood transport, fresh produce and last-mile cold delivery, so the same platform can be deployed wherever temperature-sensitive goods move or sit in storage.

Problems We Solve
Cold Chain Risks PolarGrid Helps You Manage
Common operational gaps that lead to spoilage, compliance failures and disputed claims.
Delayed Alerting
Issues are discovered after delivery instead of in the moment, when there is still time to act.
Door-Open Incidents
Unrecorded door openings during transit or storage quietly break the cold chain.
Lack of Shipment Visibility
Teams cannot see where a shipment is or how it is holding up until it arrives.
Manual Compliance Records
Spreadsheets and paper logs make audits slow and error-prone.
Product Spoilage & Claims
Without clear evidence, spoilage disputes and claims take longer to resolve.

FAQ
Cold Chain Monitoring Questions, Answered
A cold chain monitoring system uses connected sensors, GPS trackers and cloud software to track temperature, humidity and location data for perishable or temperature-sensitive goods throughout transport and storage, helping teams catch issues before they cause spoilage or compliance failures.
Yes. PolarGrid's cold chain solution is designed to work with refrigerated trucks, reefer containers, cold rooms and cold-storage facilities, connecting sensors and trackers to a single monitoring dashboard.
Depending on the sensors and gateway deployed, the platform can monitor temperature, humidity, door open/close status, GPS location, speed, ignition, sensor battery level, device power, route deviation, geofence entry and exit, trip duration and reefer unit status where supported.
Alerts are generated when readings cross configurable thresholds you define for each shipment, vehicle or storage location, so your team is notified as soon as a reading moves outside a safe range.
Yes. The platform stores historical readings so you can review temperature and humidity trends, trip-level excursion history and compliance reports for audits or internal quality reviews.
Yes. The platform is built to work with BLE temperature sensors and BLE temperature-and-humidity sensors, along with wired probes and door sensors, depending on what your deployment requires.
The platform is designed with REST API and integration capability in mind, so cold chain data can be connected into an existing fleet management, ERP or reporting system as part of a deployment plan.
Yes. The cloud dashboard is web-based and responsive, so you can review live status, alerts and trends from a desktop, tablet or mobile browser.
