The spherical shaped tip design allows for a wide area of contact with the sample. This permits a faster electrode response with a higher degree of stability. The bulb is protected by a PEI sleeve that gives the electrode resistance against mechanical stress.
Polyvinylidene fluoride (PVDF) is a plastic that is resistant to most chemicals and solvents. It has high abrasion resistance, mechanical strength, and resistance to ultraviolet and nuclear radiation. PVDF is also resistant to fungal growth.
This type of junction is often used on electrodes with polymer electrolytes. Porous polytetrafluoroethylene (PTFE) is a hydrophobic material that is available with different porosities that helps to minimize clogging. Because of its chemical advantages, PTFE is widely used in industrial applications.
Double Junction Technology
In order to reduce normal contamination coming from industrial use, these electrodes combine a polymer reference and double junction technology. With this technology, no refilling is required and the electrode can be used in samples such as organic compounds, proteins and heavy metals.
Features a built-in amplifier, which allows for measurements to be taken far from the location of the instrument without requiring a transmitter.
The 1/2” NPT thread of the HI1001 front end allows for in-line installation while the 3/4" threads on the back end (cable side) allows for submersion mounting.
