with a dew point of -20°C or less, and free of dust and oil mist.)
Consumption; Approx. 1 Nl/min
Material in Contact with Gas:
SUS 316 (JIS), Zirconia, SUS 304 (JIS) (flange), Hastelloy B, (Inconel 600, 601)
Construction:
Heater and thermocouple replaceable construction.
Non explosion-proof JIS C0920 / equivalent to IP44D.
Equivalent to NEMA 4X/IP66 (Achieved when the cable entry is completely sealed with a cable
gland in the recirculation pressure compensated version.)
Terminal Box Case:
Material; Aluminum alloy
Terminal Box Paint Color:
Case; Mint green (Munsell 5.6BG3.3/2.9)
Cover; Mint green (Munsell 5.6BG3.3/2.9)
Finish:
Polyurethane corrosion-resistant coating
Gas Connection:
Rc1/4 or 1/4FNPT
Wiring Connection:

Installation:
Flange mounting
Probe Mounting Angle:
Horizontal to vertically downward.
When the probe insertion length is 2 m or less, install at an angle from the horizontal to a
vertically downward orientation.
When the probe insertion length is 2.5 m or more, mount vertically downward orientation (within ±
5°). If using a probe protector, install at an angle between the horizontal and a vertically
downward orientation (within ± 5°).
