• The same applies to the high temperature probe adapter with a probe made of silicon carbide
(SiC).
• A gasket should be used on the flange surface to prevent gas leakage. The gasket material
should be selected depending on the characteristics of the sample gas. It should be heatproof and
corrosion-proof. The parts, which should be supplied by the user, are listed in Table 3.1.

A high temperature detector should be mounted as follows:
(1) It is recommended to mount the detector vertically. When it is impossible due to the physical
arrangements and the detector is mounted horizontally, ensure that the probe tip be placed no
higher than the probe base.
(2) When mounting a high temperature probe adapter, be sure to insert a gasket between the
flanges to prevent gas leakage. When the furnace pressure is negative, ensure that there is no
leakage of air into the detector.
(3) When mounting the detector in a position other than vertical, the cable inlet should face
downward.
(4) When installing the detector in a low-temperature location such as in the open air, cover the
probe adapter including the ejector with a heat insulator (e.g. ceramic wool) to keep it warm and
to prevent condensation of drain on the ejector.

When using an SiC probe, mount the probe vertically
with an allowable tilt of ± 5°.
