PS-100A Series Handheld Standard Capacitive Thin Film Vacuum Gaugeexplanation

I. Overview

PS-100A seriesHandheld standard capacitance film vacuum gauge is a high-precision vacuum measuring instrument developed by our company, which can be used for outdoor and mobile workOn site vacuum gauge and vacuum gauge calibration、For example:Vacuum system equipmentChemical distillationAir conditioning, refrigerator, car engine fault diagnosisVarious vacuum containers, vacuum furnaces, vacuum distillation laboratories, vacuum freeze-drying and dryingTransformer vacuum degree, chemical pipeline container sealing detection, etcOn site inspection of vacuum degree.

Handheld standard capacitive thin film vacuum gaugeAdopting foreign methodsSilicon integrated vacuum sensor or small sizeHigh precision capacitive thin film vacuum gauge,It is fundamentally different from traditional handheld resistance meters and thermocouple meters.High precision,Wide rangeGood stability、Not affected by different types of measuring media such as oil stains, water vapor, and gases,The measured pressure value is independent of the gas composition (without the need for coefficient correction),andGot itendurestrongCorrosive (316L)The models of PTFE process connectors are optional and suitable for more demanding chemical conditions .

Another significant feature of the PS-100AP series products is their good repeatability in measurement, wide range, high resolution, and good linearity throughout the entire process. They are suitable for use as vacuum pressure standards for corresponding ranges of 0.5 or 0.25. This is a traditional vacuum gauge. When purchasing standards, the company is responsible for sending them for inspection and obtaining the corresponding CNAS qualification certificate for accuracy level.
