• Seamless connectivity via local WiFi infrastructure
  Leverages existing facility WiFi networks for continuous, real-time wireless data transmission. Once connected, the logger automatically uploads temperature readings directly to the cloud platform or local servers, eliminating the need for complex wiring pipelines or manual data extraction while ensuring data availability across the entire facility.

• High-accuracy temperature sensing with external probes
  Features premium external sensors that deliver precise ±0.5℃ temperature accuracy. Operating across a wide measurement range of -30℃ to +70℃, it provides robust, continuous temperature tracking perfectly tailored for general cold storage, ambient warehouses, refrigerators, and freezer environments.

• Instant alerts via SMS, Email, and App Push
  Never miss a critical temperature excursion. The logger triggers immediate push notifications via SMS, email, or the FreshLink App the exact moment thresholds deviate from pre-configured limits, enabling managers to initiate rapid corrective actions and safeguard high-value inventory around the clock.

  Engineered for maximum digital compatibility with modern supply chains. The system supports direct data streaming into local infrastructure, private clouds, or leading third-party enterprise platforms (including ERP, WMS, and custom IoT networks), allowing businesses to establish centralized control and tailored monitoring workflows.

• Continuous power supply with battery backup
  Designed for absolute data integrity in volatile operating conditions. The device runs continuously on an external power adapter, supplemented by 3×AA batteries. This dual-source power architecture ensures uninterrupted logging and zero data gaps during sudden facility power outages.

• Flexible installation and rapid facility deployment
  Adapt to any warehouse layout within seconds using versatile mounting options. Utilize the industrial-grade Screw Mount for secure, permanent wall placement in high-traffic zones, or leverage the heavy-duty Velcro Strip for quick, drill-free deployment on temporary fixtures, glass, or metallic surfaces without damaging the infrastructure.
