NOTE:
by request of the Customer changes may be introduced
in the measurement instruments (gas analyzers) of ASEC
in terms of increasing and decreasing the number of measured
parameters with appropriate matching of mounting points,
operating conditions, current consumption values, types
and values of output signals. In particular, RSC Energia
finalizes its work on measurement systems designed to
measure dust, volumetric activity of radioactive gases
and aerosols and other environmental parameters.
