Application Example Chemical Engineering, In chemical engineering inflammable solvents with high vapor pressure are frequently used. Together with air they can build explosive composites.
When oxygen-sensitive products are treated in laboratory reactors, the process is usually carried out under vacuum or inert gas atmosphere with well defined pressure. However, pressure must not fall below a specific limit since many of those substances tend to bumping.
The VD82EX vacuum meter is certified according to ATEX II 2G EEx ia IIC T4 for use in explosive areas. With this instrument the pressure inside the flask or reactor can be measured reliably and safely no matter what kinds of inflammable vapors may be present.
