🌊 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

The Ellenex CDO2-L is an industrial-grade, LoRaWAN-enabled optical dissolved oxygen sensor designed for long-term, low-maintenance monitoring in water and environmental applications. Using a luminescent optical measurement principle compliant with ASTM D888-05, the CDO2-L delivers high-accuracy dissolved oxygen readings without the need for recalibration. It supports measurement ranges of 0–20 mg/L, 0–20 ppm, and 0–200% saturation, with fine resolution and integrated temperature compensation, making it suitable for regulatory reporting, wastewater treatment, and surface or marine water monitoring.
Built for remote and harsh environments, the CDO2-L features an IP68-rated stainless steel 316L sensor head and a UV-protected enclosure with optional cylindrical or rectangular form factors. An ultra-low-power design, powered by a replaceable internal lithium battery, enables over 5,000 readings and transmissions—typically exceeding five years of field operation. The device operates on LoRaWAN Class A (Class C optional), supports OTAA and ABP activation, and is compatible with all major LoRaWAN frequency bands and network providers.
The sensor is preconfigured for out-of-the-box deployment and supports over-the-air configuration and firmware updates via LoRaWAN downlinks. Data can be visualized and managed through the Ellenex white-label IIoT platform or integrated directly into leading cloud and industrial IoT platforms such as AWS, Azure, and Siemens MindSphere via APIs. This makes the CDO2-L a scalable and reliable solution for continuous dissolved oxygen monitoring across water, agriculture, industrial, and environmental use cases.
