Rechargeable Composite pH Electrode E201C What it is A plasticshell rechargeable composite electrode that combines a glass sensing element and a reference electrode in a single unit. Designed for use with standard pH meters in industry, healthcare, and research. Wide pH range Meets 0 to 14 pH for accurate measurements across strong acids, bases, and neutral samples. Temperature resistance Operates reliably from 0 to 60 C, delivering stable readings in different environments. Durability and ease of use Plastic housing for durability and corrosion resistance. Integrated design reduces maintenance and connection issues. Rechargeable design lowers ongoing costs. Key benefits Simplifies setup by replacing separate glass and reference electrodes. Compatible with common pH meters. Produces stable, low drift readings across a wide range of samples. Use scenarios 1) Quality control in chemical manufacturing and pharmaceutical production. 2) Environmental monitoring of water and wastewater. 3) Educational and research labs for teaching pH concepts and conducting experiments.
