PH Value Detection Rechargeable pH composite electrode with a plastic shell construction combines glass and reference electrodes for reliable performance in industrial, research, and other applications. Includes a sensor module and an electrode probe controller functionality for pH setup. Sensor Module Compatibility Designed for acidometers requiring E201C type probes, this black pH electrode integrates stably into existing systems and supports accurate realtime measurements across diverse testing environments. Electrode Probe Controller Performance Delivers sensitivity with a theoretical slope not less than 98.5% at 25 C and a zero offset around pH 7 ± 0.5, enabling precise readings over the wide 0 to 14 pH range suitable for demanding laboratory and field conditions. Extended Functionality Fast response time of ≤ 1 min allows immediate detection of pH changes, and operation from 0 to 60 C supports lasting function in variable climates and enhances control during continuous processes. Applications In chemical processing and industrial quality control where stable pH monitoring is critical. Research laboratories requiring realtime pH measurements with quick response. Field testing and environmental analysis conducted under varying ambient temperatures.
