Milwaukee SE220 – Lab Grade Double Junction pH Probe for Milwaukee MW101 and MW102 PRO meters
The Milwaukee SE220 is a high-quality laboratory-grade pH electrode designed for precision measurements in demanding environments. It is fully compatible with Milwaukee MW101 and MW102 PRO meters, as well as any other pH meter equipped with a standard BNC connector.
The double junction design minimizes clogging and contamination of the reference junction, ensuring more stable and accurate readings even in complex or contaminated samples. The gel-filled system eliminates the need for refilling electrolyte, making maintenance simple and reducing downtime. The resin body provides excellent chemical resistance and mechanical durability, ideal for both laboratory and field applications.
The spherical glass tip ensures accurate measurements and quick response, while the durable 1-meter cable with BNC connector guarantees reliable connectivity.
