Overview
FANGZHOU FZ-680 is a 2-in-1 planar Electrode designed for special laboratory samples, especially for pH measurement of solid and semi-solid soft, wet surfaces. It uses a flat-head sensitive film and a plastic shell structure to effectively contact and measure the pH value of samples such as Agar foster, meat products, dough, paper, skin, cheese, jelly, etc.
Features
1. Planar sensitive film design for surface measurement of solid and semi-solid samples.
2. Plastic shell branch pipe, sturdy and durable.
3. Adopt Ag/Agcl single salt bridge reference structure.
4. Ring sand core salt bridge liquid junction.
5. Can not be filled with internal reference solution, easy to maintain.
6. BNC standard interface, strong compatibility.
Principle
FZ-680 two-in-one planar Electrode works based on the principle of potentiometry. When its flat-head sensitive film (pH Glass film) contacts the sample, the two sides of the film generate a potential difference due to different hydrogen ion activities, which is proportional to the pH value of the sample. At the same time, the Ag/Agcl reference system inside the Electrode forms a stable electrochemistry circuit with the sample through the annular core salt bridge, so that the pH value of the sample can be accurately calculated by measuring the electromotive force.
Applications
Suitable for pH measurement of solid and semi-solid soft, wet surfaces. Such as: Agar foster, meat products, dough, paper, skin, cheese, jelly.
