METTLER TOLEDO™ InLab™ Science pH Electrodes

A pH electrode featuring a special glass body which is resistant to corrosive or organic samples, and is ideal for high temperatures and biological media. The high electrolyte outflow prevents contaminants from entering and clogging the junction, which would interfere with the reading.
