Technical Parameters: Temperature Range: 0~70℃ Dissolved Oxygen Response Time: 30 seconds to reach 95% (at 25℃) Dissolved Oxygen Range: 0~40 mg/L Temperature Compensation: Pt1000 Features: 316L stainless steel housing Interface: PG13.5 Specifications: Cable length 1.5 meters Connection Method: Aviation connector Applications: Aquaculture, wastewater, and sewage treatment fields. Key Features: - Original American-made membrane head, specifically designed for ppm-level dissolved oxygen measurement in boiler feedwater and condensate, widely used in environmental and sewage applications. - Three-electrode system for superior performance: includes a platinum cathode, silver anode, and an additional silver reference electrode, significantly enhancing signal stability and accuracy with zero-point stability. - Minimal residual current drift over long-term use, meeting ppm-level measurement requirements. Fast response time with a built-in self-consuming electrode that automatically depletes residual oxygen in the electrolyte.
