�� High-Accuracy Optical Dissolved Oxygen Measurement: Utilizes a luminescent optical sensing principle approved by ASTM D888-05, delivering precise dissolved oxygen measurements without the need for recalibration. Supports wide measurement ranges including 0–20 mg/L, 0–20 ppm, and 0–200% saturation with resolution down to 0.01 and accuracy up to ±0.1 mg/L, making it well-suited for regulatory and industrial monitoring applications �� Ultra-Low Power with Multi-Year Battery Life: Powered by a built-in, replaceable 3.6 V lithium battery, the CDO2-L supports over 5,000 readings and 5,000 LoRaWAN transmissions—translating to more than 5 years of operation in most use cases. Optional external power configurations are available for extended deployments or specialized installations �� LoRaWAN Connectivity with Global Network Compatibility: Fully compliant with LoRaWAN Class A (Class C optional) and compatible with major frequency bands including AS923, EU868, US902-928, and AU915-928. Supports OTAA and ABP activation, configurable sampling intervals via downlink, and seamless integration with leading LoRaWAN network servers such as TTN, Helium, Actility, Senet, and more ��️ Rugged Outdoor-Ready Design: Engineered for harsh environments with an IP68-rated stainless steel 316L sensor head (titanium optional) and UV-protected enclosure rated IP66/IP68 depending on configuration. Designed to withstand pressures up to 5 bar, making it reliable for long-term deployment in water, wastewater, marine, and industrial environments �� Cloud-Ready Data Management & Configuration: Supports over-the-air parameter configuration and firmware updates, with direct integration into the Ellenex white-label IIoT platform or third-party cloud platforms via APIs (AWS, Azure, Siemens MindSphere, Ubidots, TagoIO, and more). Features include device inventory management, configurable alarms, data export, multi-tenant access control, and scalable enterprise integration
