Analysis of Technical Features of Chemical Vacuum Gauges

The -60kPa chemical vacuum gauge is specially designed for accurate measurement of vacuum levels in industrial processes. Its core functions include negative pressure environment monitoring and pressure fluctuation warning. This device uses imported high-precision differential pressure sensors with a measurement range covering 0 to -60kPa, supporting dual-unit display in kilopascals (kPa) and millimeters of mercury (mmHg), with an accuracy of ±0.2% FS, meeting the stringent requirements for minor pressure changes in the chemical and pharmaceutical fields. Its four-and-a-half digit display and real-time data storage capabilities allow for simultaneous recording of pressure curves, facilitating the traceability of process parameters. The product is certified for explosion protection, with a casing made of 304 stainless steel and equipped with a fluororubber sealing ring, ensuring stable operation in corrosive gas or high-temperature environments (up to 140°C). Additionally, the vacuum gauge features a built-in pressure calibration module, supporting on-site zero and range adjustments to reduce measurement deviations caused by environmental factors, making it especially suitable for scenarios that require maintaining a constant negative pressure of -60kPa, such as seal testing of vials and vacuum drying.
