https://www.aiotkart.com/web/image/product.template/17667/image_1920?unique=90db3c5

The Dragino DR-PH01 is an industrial-grade RS485 pH sensor designed for continuous water quality monitoring in wastewater plants, industrial processes, environmental water systems, and municipal utilities. It measures pH from 0 to 14.00 with high precision and features automatic temperature compensation for stable and reliable readings.The DR-PH01 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 pH data and wirelessly transmits it to a LoRaWAN® server for remote monitoring, logging, and compliance management.Built with IP68 waterproof protection, a double salt bridge reference electrode design, and a 5-meter industrial cable, this solution is engineered for long-term deployment in demanding water environments.
