Cold Chain Monitoring
Every degree out of range
is traceable loss
, or a
health risk.
Product loss, a regulatory hold or a customer complaint all start at the same point: a temperature failure no one was monitoring. Continuous monitoring, instant alerts and full traceability, from the sensor to the audit report.
← Back to SolutionsWithout data, you can't
demonstrate technically that the chain held.
A cold room that loses temperature overnight. A batch of medicines exposed to excessive heat in transit. Product expired ahead of schedule because humidity was out of control for weeks.
The problem is always the same: the failure happened before any alertBy the time it's discovered, the damage is done, and without a monitoring history there is no way to know when it started.
For the health authority, for cargo insurance and for the customer at the other end of the chain, the only accepted answer is continuous data with traceability by batch and by device
Product loss
Food and medicines outside the temperature range lose their shelf life ahead of schedule, and the loss is immediate, calculable and avoidable.
Regulatory hold and seizure
The health authority can hold the batch, seize the cold room and require a recall, with no room to contest when there is no monitoring history.
Regulatory non-compliance
Good Distribution Practice (GDP) requires documented temperature control at every stage of the chain, from the warehouse to the point of delivery.
Liability and recall
Without monitoring data, the company has no way to limit the scope of a recall or to contest liability in a consumer-harm lawsuit.
The standard defines the range.
The sensor records reality.
Each segment of the cold chain has its own specific regulatory requirement. PLEXOR delivers the data, and the report, that every audit requires.
Good Distribution Practice (Pharmaceutical)
Requires continuous temperature and humidity control across the entire medicine distribution chain, with documentation traceable by batch and by device.
Medical Devices & Diagnostics Storage (GDP)
Sets storage and transport conditions for medical devices and diagnostic reagents, including critical temperature ranges.
Food Safety Storage (HACCP / cold chain)
Defines temperature requirements for the storage, processing and distribution of food, including continuous logging and documented corrective action.
Blood & Blood Products Storage (cold chain)
Blood banks and blood centers have strict temperature requirements for storage; any deviation requires immediate tracing and documented disposal.
Monitoring at the critical point.
Alerts before the loss.
Hardware with a PT100 probe placed exactly on the product, fluid or critical surface, combined with a native IoT platform that records, alerts and documents continuously.
The external PT100 probe goes exactly where the product is, inside the cold room, in the batch, in the fluid. The sensor doesn't measure the air: it measures what matters.
Alarms by threshold, envelope and time out of range. Notifications by email, webhook and REST API (SMS as an add-on) sent at the moment of the deviation, not hours later when the product has already been compromised.
PDF with device ID, company details, time-series charts and regulatory ranges. Traceable by batch, by cold room and by period, ready for audit.
Continuous retention, logging every offline period. In a regulatory or legal proceeding, the history is the only accepted evidence. Here it exists and is exportable at any time.
Available for any PLX model. Required by health authorities, metrology bodies and ISO audits, issued by PLEXOR as an optional or periodic service.
Management of multiple cold rooms and sites on a single platform. Each location with segregated access, from the distribution center to the pharmacy network.
Deployed in days.
Traceability from
the first data point.
Installation
Device installed and PT100 probe placed at the critical point. Plug-and-play, no construction.
Configuration
Temperature ranges configured per cold room. Alerts defined by contact and by severity level.
Monitoring
Data sent continuously. Instant alert by email, webhook and REST API (SMS as an add-on) at the moment of any deviation.
Documentation
Report generated with one click. History exportable by cold room, period and batch, audit-ready.
The right product
for each critical point.
PLX-M family with external PT100 probes, to monitor where the product is, not just the surrounding environment.
- PT100 LT probe for sub-zero temperatures
- Internal ambient temperature monitored simultaneously
- Ideal for freezing and ultra-low temperature rooms
- Real-time alerts for out-of-range deviations
- Traceability by device ID in every report
- Supports pharmaceutical GDP requirements
- Probe positionable on the product, shelf or fluid
- Report with device ID, supporting GDP documentation
- Calibration certificate available as a service
- Multi-room and multi-site on the same platform
The data exists.
So does the evidence.
The PLEXOR platform records every reading with a unique device identifier, turning monitoring into real traceability for GDP, insurance and audit.
Audit-ready report with one click
PDF with device ID, company details, time-series charts and regulatory ranges. Traceable by cold room and by period.
History of up to 5 years
Continuous retention, logging every offline period. In audits and legal proceedings, the full history is exportable as PDF or CSV at any time.
Instant alert on deviation
Notification by email, webhook and REST API (SMS as an add-on) the moment the temperature leaves the range. Configurable by cold room, by product and by criticality level.
Integrated calibration management
Control of certificate expiry dates with an automatic warning before the deadline, with the full traceability required by metrology bodies and health authorities.
Offtime logging
Every period a device is offline is logged, essential for proving continuity of monitoring in regulatory audits.
Multi-room with segregated access
Management of all cold rooms and sites on one platform, with access control by location and by contact.
Cold chain ROI
is the easiest to calculate.
❌ Without monitoring
- 🥩Loss of an entire batch, product cost plus regulatory disposal cost
- 🚨Regulatory hold, seizure of the cold room and operational shutdown
- 📋Regulatory non-compliance, fines, operating restrictions and risk of license cancellation
- 💸Recall with no scope limit, without data there is no way to prove the failure was isolated
- ⚖️Liability with no defense, no data means no record
✓ With PLEXOR
- 🔔Alert before the loss, corrective action while the product is still in range
- 📄GDP report in one click, audits with no improvisation
- 📅History of up to 5 years, recall scope limitable with real data
- 🔬Integrated calibration certificate, metrologically valid traceability
- 💡Direct ROI, cost of monitoring vs. cost of a single lost batch
From the cold room
to the truck body.
Any point in the chain where temperature is critical, and needs to be documented.
Frequently asked
questions.
Does the system meet Good Distribution Practice (GDP) requirements for medicine storage?
The PLEXOR platform generates reports with full traceability, sensor identification, timestamp and temperature history, which support the documentation required under Good Distribution Practice (GDP) for the storage of medicines and pharmaceutical inputs.
What happens when the temperature exceeds the configured limit?
The platform sends an instant alert by email, webhook and REST API (SMS as an add-on) to the assigned contacts. The event is recorded with a timestamp in the auditable history, making it possible to identify the duration and magnitude of the deviation for product impact analysis.
Can the same system monitor freezing and refrigeration rooms at the same time?
Yes, provided the appropriate sensor is used. The PLX-M200 is available in the LT version (down to –80 °C, for deep freezing) and the ST version (up to +80 °C, for refrigeration). Both run on the same platform, with unified dashboards and alerts.
The record that the chain held.
Every connection and event recorded with date and time, the continuity history that the health authority, the insurer and the customer at the end of the chain ask for.
