DR-ORP1 Water Oxidation - Reduction Potential Sensor

https://www.aiotkart.com/web/image/product.template/17666/image_1920?unique=553d66a

The Dragino DR-ORP1 is an industrial-grade Oxidation-Reduction Potential (ORP) sensor designed for continuous water quality monitoring in industrial, municipal, and environmental applications. It accurately measures ORP levels from -1999 mV to 1999 mV using a high-purity platinum electrode, ensuring stable and reliable performance in demanding water environments.The DR-ORP1 integrates seamlessly with the Dragino WQS-LB, a LoRaWAN-enabled water quality converter that supports up to three probes simultaneously (EC, pH, DO, ORP, Turbidity, and Chlorine). The WQS-LB collects ORP data and transmits it wirelessly to a LoRaWAN® server for real-time remote monitoring and control.With IP68 protection, RS485 communication, automatic temperature compensation, and multi-year battery-powered operation via the WQS-LB, this solution is ideal for long-term field deployment across India.
