A micron refers to a micrometer of mercury.
Pa=N/m² : The Pascal (Pa) is the SI unit, 1 Bar = 10E5.Pa = 101 kPa = 0.1 MPa A pressure of 1 Pa applied on a surface A=1m² generates a force F=1N (1N=1 kg.m.s-²). If a pump is rated for 25 in.-Hg, it can achieve 83.4% (25 29.92) of a sea level perfect vacuum. These applications will - due to browser restrictions - send data between your browser and our server. To adjust a pump rating, think of that rating as a percentage of atmospheric pressure at sea level. 0000005876 00000 n 0 endstream endobj 5 0 obj <> endobj 6 0 obj <>/Type/Page>> endobj 7 0 obj <> endobj 8 0 obj <> endobj 9 0 obj <>stream 0000012171 00000 n 3. micron.

As vacuum technology advanced, it became necessary to have a more precise vacuum measurement unit than the mm of Hg. <<6B9069B7FDF61543B98C2DA92637C0DF>]>> Vacuum is commonly measured relative to atmospheric pressure, and represents a negative gauge pressure but still a positive absolute pressure.
