Model NGA2000 CLD
ADDENDUM
MATRIX POSITION 12, VALUE “G”
1.0 OVERVIEW
The following special modifications to your
standard CLD Analyzer (PN 194005) are
made as specified by the “G” designator cho-
sen for the 12
th
position of the product matrix
and supercedes the information supplied in
this manual.
2.0 SPECIFICATIONS
Range: 10, 50, 300 PPM
Noise: 1% Range
T90 Response: 1-2 sec.
Sample Flow: 3 L/min.
Sample Pressure: 2 psig
Conformity: Non-Linear
3.0 PHYSICAL MODIFICATIONS
Flow Sensor Removal
The flow sensor (PN 902931) has been re-
moved. This does not affect the operation,
accuracy or safety of the analyzer. It means
that the bypass flow is no longer measured.
Therefore, the platform display has been
modified to show:
Sample pressure
Block temperature
Ozonator
Converter temperature
The CLD physical parameter will now indicate
zero sample flow, and generate a validity and
warning alarm which will not be displayed and
should be disregarded.
Component Changes
The following parts have replaced the stan-
dard components:
•
Pump Capillary PN 660405
•
Detector 200 cc/min 2 psig PN 660404
•
Back Pressure Regulator 2 psig PN
660400
4.0 FLOW DIAGRAM
CLD module with value “G” in matrix position
12, Figure 1-1 Flow Diagram is replaced with
Figure 1-1 on this addendum.
