Teledyne 6200E - Sulfides Analyzer - Manual (Page 51)

Model 6200E Instruction Manual Optional Hardware and Software
M6200E Rev: A1 51
CAUTION
Gas flow must be maintained at all time for units with a permeation tube installed.
Insufficient gas flow allows gas to build up to levels that will contaminate the
instrument.
5.4.3. IZS Permeation Tubes (Options 53, 55 & 57)
Several replacement permeation tubes are available for the IZS option. They are identical in size
and shape but are designed to have different effusion rates. Since the M6200E can be configured
as either a H
2
S or SO
2
analyzer, both types of permeation tubes are included here.

Each tube comes with a calibration certificate, traceable to a NIST standard, specifying its actual
effusion rate of that tube to within ±5% when immersed in a gas stream moving at the specified
flow rate. This calibration is performed at a tube temperature of 50° C.
NOTE
The instrument can only be fitted with one type of permeation tube at a time. Therefore
the IZS option can only be used to calibrate or check the instrument for one gas, H

S or

, but not both.
5.4.4. Zero Air Scrubber Maintenance Kit (Option 43)
This kit includes the following items needed to refurbish the zero air scrubber, included with the
IZS valve options.
