Features

Wi-Fi / 4G / LAN Connectivity Options
Available in three dedicated hardware versions—Wi-Fi, 4G, or LAN connectivity. This allows users to select the most reliable transmission method based on their specific site conditions, whether it’s utilizing existing facility networks or bypassing IT infrastructure with a cellular (4G) solution to avoid coverage gaps.

API-ready for Diversified IoT Solutions Integration
Engineered for maximum compatibility. Seamlessly push real-time data directly to your own local servers, private clouds, or existing enterprise platforms such as ERP, WMS, and third-party IoT management systems. This ensures centralized data control and empowers you to build customized monitoring workflows within your preferred software architecture.

High-accuracy Sensing (±0.5℃) with One Optional External Probe
Max. 2 monitoring channels, available in three probe configurations to match your specific storage needs:
Standard (-30℃ to +70℃): Ideal for general cold storage, warehouses, and ambient monitoring.
Ultra-Low (-90℃ to +200℃): Designed for dry ice, liquid nitrogen storage, and industrial use.
Temperature&Humidity (-40℃ to +85℃ / 0-100%RH): Perfect for pharmaceutical, warehouse, and cold room environments.

Continuous Power with 3×AA Battery Backup
External power adapter supports continuous operation. The three AA batteries provide backup power during emergency power interruptions.

Real-time Alerts via SMS, Email, and App Push
Provides an instantaneous safety net. Get notified immediately from “Freshlink” when temperature or humidity deviates from preset thresholds, enabling proactive risk mitigation and ensuring the safety of your inventory 24/7.
