Recommended Preventive Maintenance Spare Parts
This section lists the recommended spare parts to have readily available
for the Model 920 Analyzer to ensure the analyzer and its sample system
operate at peak efficiency.
IMPORTANT SPARE PARTS INFORMATION
Spare Parts for your analyzer may vary from those included in this
section. This can be due to applications other than SO

, nonstandard
Measuring Cells, or optional equipment.
If a Sample Conditioning Unit (SCU) is used, refer to the “AMETEK
SCU (Probe)” or “M&C Probe” Preventive Maintenance Parts list.
Before ordering spare parts, refer to the “Supplemental Information”
section of this manual for a
Custom Spare Parts list. If included, use
those Part Numbers; if not, use the Part Numbers listed in this section.

Optical Bench/Measuring Cell Spare Parts
The replacement of these parts is required as part of the Analyzer
Preventive Maintenance Schedule (Chapter 5). It is also necessary to have
these parts on hand in case the parts become damaged or contaminated,
and need to be replaced earlier than listed in the recommended schedule.
In the event of natural degeneration, damage, or other failure of a
Source Lamp, AMETEK recommends changing out both Source
Lamps to ensure optimal operation.
(*) Note the ordering part numbers for the different Source Lamps
and order only the appropriate type and quantity of Source Lamps.
The source lamp configurations vary for different applications; do not
interchange the lamps from their original positions. To verify the lamp
type, open the analyzer and check the label on each lamp.
