Leybold PTR225 Product Details
Leybold PTR225 Introduction
Leybold PTR225 is a high-performance vacuum measurement sensor,widely used in vacuum systems for accurate measurement of low pressure ranges.It uses the Penning gauge principle and can measure extremely low pressures,suitable for scientific research,semiconductor manufacturing,vacuum coating and other fields.
Working principle of PTR225
Penning gauge is a cold cathode discharge tube.Under the action of a high-frequency electric field,gas molecules are ionized to produce ions.By measuring the ion current,the gas pressure in the vacuum chamber can be calculated.PTR225 uses this principle to achieve accurate measurement of low pressure ranges.
Main features of PTR225
High sensitivity:Able to measure extremely low pressures,usually in the range of 10^-9 to 10^-2 mbar.
Wide measurement range:Covers a wide range of pressures from low vacuum to ultra-high vacuum.
High stability:Has good long-term stability and repeatability.
Strong anti-interference ability:Not easily affected by external interference,such as magnetic fields,electric fields,etc.
Compact structure:Compact design,easy installation.
Applications of PTR225
Vacuum system monitoring:Used to monitor the operating status of the vacuum system to ensure the stability of the vacuum degree.
Leak detection:Used to detect the leak point of the vacuum system.
Thin film deposition:Used to control the vacuum degree during the thin film deposition process.
Scientific research:Widely used in scientific research in the fields of physics,chemistry,etc.
