The side facing the medium chamber is
provided with moulded grooves set at
90° angles. The moulding process increases
the resistance of the glass
grooves to wear; the “skin” which the
glass attains during moulding gives it
maximum smoothness and hardness.
This makes it extremely resistant to the
attack of boiler water.
Up to 35 bar saturated steam, reflex
glasses provide the optimum solution:
they are corrosion resistant and provide
an absolutely clear indication.
Reflex glasses can be used with all media
except steam at service conditions
up to 400 bar or temperatures up to
