Talk to our team SMART Cold Chain IQ connects your temperature-sensitive environments to real-time monitoring, intelligent alerts and audit-ready reporting—so your team can act before risk becomes loss.
From the moment a sensor reads temperature, humidity or door status to the instant your team receives an alert, SMART Cold Chain IQ keeps every critical condition visible and actionable.

See how one changing condition becomes an actionable alert and a complete, time-stamped compliance record—without waiting for the next manual check.

SMART Cold Chain IQ adapts to the operational realities of regulated, temperature-sensitive industries—from a single critical fridge to a multi-site network.

SMART supported Life Healthcare with the rollout of continuous temperature monitoring across pharmacy fridges and dispensing areas throughout its hospital network. Following the success of the initial deployment, monitoring expanded into oncology, operating theatres and renal units.
Different industries carry different risks, but the requirement is consistent: know what happened, respond early and retain evidence that stands up to operational and quality review.
Medicines, vaccines and biologics can lose stability, efficacy or usable shelf life when approved storage conditions are breached.
Continuous records, real-time alarms and excursion evidence help quality teams investigate quickly and protect product integrity.

Automated monitoring replaces gaps between manual checks and provides staff with early warnings, escalation and evidence for corrective action.

Zone-level monitoring reveals hot spots, equipment drift and excursions, supporting faster response and defensible release decisions.
Product-specific requirements include R638 for food; PPECB cold-chain controls and the Perishable Products Export Control Act for regulated exports.

A temperature mapping study shows how conditions vary throughout a controlled space—not only where a permanent sensor happens to be. Where relevant, humidity can be mapped alongside temperature. We use calibrated data loggers and a defined protocol to help you qualify storage areas, improve sensor placement and build defensible evidence for quality reviews.
Discuss a mapping studyIdentify temperature variation across rooms, zones, shelving and operational areas.
Verify uniformity, recovery performance and hot or cold spots under representative conditions.
Map medical, vaccine, laboratory and food fridges to support safe sensor placement and qualification.
Understand vertical and horizontal gradients across high-volume or temperature-controlled storage.
Profile cargo areas and transport routes to reveal airflow gaps, door-event impact and in-transit risk.
Multiple calibrated loggers record conditions at the same time. The visual builds a temperature profile that exposes localised hot spots, stable zones and the best positions for permanent monitoring.
Studies can include temperature and humidity profiling, empty and loaded conditions, door-opening tests, power-failure recovery, seasonal mapping and transport-route profiling—matched to your risk, operation and approved protocol.
Identify excursions early and give the right people the information to respond faster.
Maintain consistent, accessible monitoring records without relying on manual checks.
