Intended Use
The Pirani Standard Gauges PSG500/-S, PSG502-S,
PSG510-S, PSG512-S have been designed for vacuum
measurement of gases in the pressure range of
5×10
-4 … 1000 mbar.
They must not be used for measuring flammable or combus-
tible gases in mixtures containing oxidants (e.g. atmospheric
oxygen) within the explosion range.
They can be operated in connection with an INFICON con-
troller or with another controller.

General Safety Instructions
• Adhere to the applicable regulations and take the nec-
essary precautions for the process media used.
Consider possible reactions between the materials and the
process media.
Consider possible reactions (e.g. explosion) of the process
media due to the heat generated by the product.
• Adhere to the applicable regulations and take the neces-
sary precautions for all work you are going to do and con-
sider the safety instructions in this document.
• Before beginning to work, find out whether any vacuum
components are contaminated. Adhere to the relevant re-
gulations and take the necessary precautions when hand-
ling contaminated parts.
Communicate the safety instructions to all other users.
