SSi Portable Hydrogen Analyzer
Rev A
Basic Operating Description:
This instrument uses the measurement of Hydrogen to display % Hydrogen (H
2
), % Dissociation
(DA), and % Ammonia (NH
3
). When the flow rates of Nitrogen, Ammonia, and Dissociated
Ammonia are manually entered, the instrument can also calculate Nitriding potential (Kn).
When the instrument is turned on, it will display % H
2
and %DA on the screen. To display
additional values (%NH
3
or Kn), see the “Instrument Configuration” screen. The 4-20mA output
on the side of the case can be set up to retransmit the any of these measurements in whatever
range is appropriate for the application.
The home screen also displays the flow of N
2
, NH
3
, and D.A. These values can be entered by the
operator when the instrument is in the mode to evaluate Kn or %DA. This is discussed further
under the Instrument Configuration section. The Menu button in the bottom left-hand corner
will take the operator to the configurable options within the controller. The Chart button in the
bottom right-hand corner of the screen will display the data trend chart.
