Specifications

Low oxygen level testing
Equipped with a non-oxidizing gas intake structure
which fills the chamber with non-oxidizing gas such
as CO
2
or N
2
for heat treatment or temperature
characteristics testing requiring low oxygen
concentration atmosphere.
Hermetically sealed configuration
The chamber is hermetically sealed to decrease oxygen
inside the chamber. The inner stainless steel plate is
seamless welded with argon gas.
O
2
concentration indicator controller (optional)
An optional O
2
concentration indicator controller
equipped with an oxygen sensor is available. It
allows precise regulation of the O
2
level throughout
the range 0.5 to 21% (using N
2
).
