LEYBOLD PTR225 Product Details
LEYBOLD PTR225 Introduction
LEYBOLD PTR225 is a high-precision vacuum measuring instrument,which belongs to the category of Penning Gauge.Penning Gauge is a cold cathode ionization vacuum gauge that can perform accurate measurements at extremely high vacuum levels.PTR225 is widely used in situations where high-precision vacuum measurement is required,such as scientific research,semiconductor manufacturing,vacuum coating,etc.
Working Principle of PTR225
The working principle of Penning Gauge is based on the ionization phenomenon of gas under the action of electric and magnetic fields.PTR225 has a ring cathode and an axial anode inside.When high voltage is applied,electrons move in a spiral motion under the action of electric and magnetic fields,colliding with gas molecules to produce ions.By measuring the ion current,the gas pressure in the vacuum chamber can be calculated.
