Online pH Analyzer DAW3001-pH with LCD Display for Clean Water
Supporting pH/ORP measurement and optional metallic antimony electrodes for hydrofluoric acid environments, the analyzer uses a universal power supply or optional DC version, with an isolated RS485 interface (MODBUS-RTU) for data transmission. With a wall-mounted design, it operates at 0～60℃ and <90% humidity. Paired with an IP68-protected pH sensor, it achieves 0-14 pH/0~50℃ measurement ±0.1 pH sensor accuracy, <30S response time, and flexible installation, suitable for diverse industrial monitoring needs.
