STANDARD SPECIFICATIONS (High
Temperature Humidity Analyzer)
Sample Gas Temperature: 0 to 700°C (Probe
only)
It is recommended to mount the cell
using inconel cell-bolts when the
temperature is greater than 600°C.
Sample Gas Pressure: - 5 to + 20 kPa (When
the pressure in the furnace exceeds
3 kPa, it is recommended to use
pressure compensated type. When
the pressure in the furnace exceeds
5 kPa, pressure compensated type is
required.)
fluctuation in the process should be
allowed.

Probe Mounting Angle: Horizontal to vertically
downward. When the probe insertion
length is 2 m or less, installing at
angles from horizontal to vertically
downward is available.
When the probe insertion length
exceeds 2.5 m, mount vertically
downward (within ± 5°) and use a
probe protector.
