The Analyser MGAprime-Q is designed for the gas analysis of flue gases,
as they are emitted from gas/oil burners, engines, or heating and power
appliances.
The analyser is intended to support the user in control and indicative
measurements in an efficient, accurate and reliable way.
The analyser is specifically not intended as a safety device or personal
protective equipment.
The analyser should not be used as a warning device to warn people
against the presence of harmful gases.
The analyser was manufactured according relevant standards and
regulations.
The analyser must be used according to instructions for the intended
use.
WARNING
Risk from manipulations to the measuring device
Operational safety hazard
►Modifications or changes to the measuring device are
not allowed.
Syntax
Please note that this manual makes use of the scientific notation of
gases (NO2), while the instrument itself and its screen shots display the
gases in upper case letter only, i.e. (NO2).
