Complete Environmental Monitoring—Completely Standalone Connect directly to your network with zero extra hardware. The COEUS series delivers industrial-grade temperature and humidity tracking without the need for a central gateway router. Operating as an entirely independent, plug-and-play unit, it links directly to your existing WiFi or 4G network to stream real-time data straight to the secure cloud. ⚡ Standalone Infrastructure: No gateway hubs, no complex base stations, and zero monthly software fees. Simply pair the device directly to the app and start protecting your inventory instantly. Key Performance Benefits Direct-to-Cloud Connectivity: Built-in WiFi or 4G network capability transmits live climate logs directly to your secure dashboard 24/7. Dual-Probe Multi-Zone Tracking: Supports up to two optional external precision probes, allowing you to monitor multiple isolated zones simultaneously across an ultra-wide temperature spectrum (-90°C to +190°C). Instant Multi-Channel Alerts: Receive immediate notifications via SMS, email, and app push alerts, supplemented by on-device visual and audible alarms the moment thresholds are breached. Local LCD Interface: High-contrast display provides on-site personnel with instant visibility over current conditions, alongside historical maximum and minimum readings. Failsafe Offline Protection: If a local network connection drops, the internal storage caches your data safely on-board and automatically uploads the complete log the second connectivity is restored. Effortless Compliance Reporting: Generate and export on-demand cryptographic data history reports to satisfy strict regulatory audits in seconds. Long-Life Rechargeable Battery: Low-power engineering delivers up to 90 days of continuous tracking on a single charge. Universal Applications Engineered to meet the most stringent international quality and compliance standards, this standalone monitoring instrument is built for: Cold Chain & Logistics: Walk-in cool rooms, industrial freezers, distribution centers, and refrigerated transit fleets. Medical & Laboratory: Pharmacies, incubators, blood banks, and clinical specimen storage. Food Production & Hospitality: Commercial food manufacturing, distribution hubs, and HACCP-compliant facilities. Critical Workspaces: Any high-value environment requiring failproof, continuous climate auditing.
