Features Moveable Sleeve Junction - The LabSen 221 pH electrode is easy to clean, especially suitable for low ion concentration solution and non-aqueous solution
It improves the stability of reference electrode and prolong the service life of the electrode
Long-Life Reference System - The LabSen 221 pH electrode adopts a long-life reference system, which is composed of a glass tube, AgCl and a reference silver wire
Special Glass Membrane - The LabSen 221 pH electrode adopts a Cylindrical glass membrane, which is highly resistent to general impact the traditional glass bulb membrane is a lot more fragile , and can be tested in high temperature samples up to 176 deg F .
The electrode is compatible with TRIS buffer solutions
The infiltration rate of the electrolyte is determined by the tightness of the sleeve during installation
The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when temperature changes
