Summer is coming. Is your cold chain ready?
Every summer, rising ambient temperatures push refrigeration systems to their limits — in distribution centers, retail display cases, and food storage rooms.
A single temperature excursion can cost thousands.
Stationary temperature monitoring is your first line of defense.
When the Heat Rises, the Risk Rises with It
For anyone responsible for food quality in logistics, retail, or storage, summer is the season of highest risk. Refrigeration units work overtime. Ambient temperatures spike. Doors are opened more frequently. And the margin between "safe" and "spoiled" becomes razor-thin.
Challenges in every sector
In Food Logistics & Distribution center
Walk-in freezers and chilled staging areas are under constant pressure during summer months. Compressors run at capacity. If a unit fails overnight or over a weekend — Who notices that? Manual checks the next morning may be hours too late. Entire pallets of products may be unsalvageable.
You can’t be everywhere. But your monitoring can!
The Testo online data loggers form a flexible, scalable system for stationary temperature monitoring — in food logistics, retail, and storage. Connected via Wi-Fi or Ethernet to the testo Smart Connect cloud, they deliver continuous, automated, audit-ready monitoring. 24/7. Even in summer.
The testo 16X family offers online data loggers for every use-case. They monitor temperature and other values like humidity around the clock — fully automated, without manual intervention. All data is transmitted continuously to the testo Smart Connect cloud. If there are deviations from previously defined standard values, alarms are triggered automatically and immediately.
The testo 162 connects directly to your existing Wi-Fi network and features an integrated display: staff can read current values on the spot at any time — no app, no login, no detour. It is HACCP-certified for temperature and available in multiple variants for temperature, humidity, pressure, and CO₂ monitoring.
The testo 164 is designed for larger facilities where running Wi-Fi to every measurement point is not practical. The compact data loggers communicate Via radio frequencies to a central gateway — one gateway per area is sufficient to cover multiple sensors across an entire warehouse or storage facility. With a battery life of up to 10 years and an IP67 rating, the testo 164 works reliably even in demanding cold and freezer environments.
The moment a configured limit is exceeded, testo Smart Connect triggers an alarm — via push notification, email, or SMS. But the system goes further than a simple alert: alarm responses can be fully configured to match your operational reality.
Alarm delays prevent false alerts from brief, non-critical fluctuations — for example during door openings or defrost cycles. Individual limit values are set per sensor, so a freezer room and a dry goods store are monitored with precisely the thresholds that apply to each.
All measurement data is stored continuously and securely in testo Smart Connect — tamper-proof, without gaps. Audit-ready, online-accessible reports can be generated, stored and exported in seconds, covering any time period and any sensor. No manual logbooks, no missing records, no last-minute audit stress.
