E201C Rechargeable Composite Electrode Construction and function The E201C is a plasticshell rechargeable composite electrode that combines a glass electrode and a reference electrode in one unit. This design provides a compact, integrated solution for reliable pH measurement. Wide pH range Measures from 0 to 14 pH, enabling accurate and reliable readings across a broad range of substances. Temperature range Operates from 0 to 60 C, allowing accurate measurements in different environments. Performance and compatibility Designed for compatibility with standard pH meters that accept composite electrodes. Durable construction supports regular testing use. Use scenarios 1. Laboratory testing in industrial, medical, and research settings where broad pH capabilities are required. 2. Industrial process control and quality assurance where stable pH measurement across varying substances and temperatures is important. 3. Educational laboratories and field testing for teaching and data collection with reliable pH readings.
