This Standard covers pressure meters with the capability of
- use with air, natural gas and LPG,
- measuring pressure in units of mbar, Pa, hPa, kPa, inH20 or PSI,
- withstanding the every-day working environment encountered by installation and service engineers
in domestic, commercial or industrial premises.
and such pressure meters may optionally be capable of
- being switchable between units by the user,
- storing and/or transmitting said measurements to a remote user
