Observe the following when connecting the gas tube.
●
Piping should be connected to the gas inlets and outlets at the rear panel of the analyzer.
●
Use a corrosion resistant tube of Teon, stainless or polyethylene to connect the instrument to
a sampling system. Even if there is a danger of corrosion, refrain from using a tube of rubber
or soft vinyl. The instrument provides inaccurate indication due to gas absorption by piping
materials.
●
Pipe connection port is Rc1/4 female thread (or NPT1/4). Piping should be cut as short as
possible for a quick response. About 4 mm inner diameter is recommended.
●
Entry of dust into the instrument may result in defective operation. Use a clean piping or
coupling.
Sampling gas inlet: Attach the gas tube to introduce gas to be measured such as one that has
completed dehumidication process and standard gases for zero and span
calibration to this inlet.
Gas ow to be introduced should be constant within the range of 0.5 L/min
±0.2 L/min.
Sampling gas outlet: Exhaust measured gas through the outlet. Attach the tube to exhaust mea-
sured gas outdoors or to the atmosphere.
Purge gas inlet: It is used for purging the inside of the total gas analyzer.
Use dry gas N
2
or instrumentation air for purge gas. (Flow rate is 1L/min or
more, and dust or mist is unallowable.)

In addition to a sample gas inlet and outlet, there is a purge gas inlet at the rear panel of the
analyzer.
When improper connection is carried out here, combustible gas, poisonous gas, and explo-
sive fumes may be accumulated into the analyzer.
