Other duties of Richmond's City Clerk include assisting the Mayor with appointments, telephone calls and clerical work as needed. Also the City Clerk is the bridge between executive and legislative, between both of these and component government units, and between all of these and the public they are pledged to serve.
A micron is a unit of linear measure in the metric system used to measure distance from one point to another. The particles and contaminants that we are trying to filter out are far smaller than can be seen with the naked eye, magnifying glass or even a low powered microscope.
A micron gauge measures the amount of air or ânoncondensablesâ and moisture in a system. The unit of measurement used is a âmicron.â The gauge is placed between the vacuum pump and the middle port of your manifold set. The lower the micron reading, the deeper the vacuum. The deeper the vacuum, the lower the amount of air and moisture in any given system.
