Standard laboratory electrodes 

In addition to the BlueLine electrodes available 

in the new design and with their 

own equipment features, such as the convenient 

sliding plug, we also offer a complete 

programme of standard electrodes for 

practically all kinds of applications in the 

laboratory and in the field. 

On the following pages, we will be presenting 

to you these highly qualified sensors 

that have proved their reliability millions of 

times: 

◗ Even more application possibilities 

◗ Selection of micro-electrodes for especially 

small sample quantities and vessels 

◗ More metal electrodes for redox potential 

measurements and titrations 

◗ Sensors for additional parameters such as 

ammonia, sodium and oxygen 

◗ Individual pH glass, metal and reference 

electrodes for specific conditions 

For further applications, you will find suitable electrodes in the corresponding chapters.
