Fig. 1 Device overview
The device monitors gases in ambient air and in the workplace.
It is available with a maximum of three sensors, which can display readings for four separate gases
(one Two-Tox Sensor can detect two toxic gases with a single sensor).
While the device can detect up to 30% oxygen in ambient air, it is approved for use only up to 21%
oxygen.
The alarm levels for the individual gases are factory-set and can be changed through the Setup Menu.
These changes can also be made through the GALAXY GX2 Test Stand or MSA Link software. Ensure
that the latest version of the GALAXY GX2 firmware or MSA Link software has been downloaded from
MSA’s website www.msasafety.com.
