OMEGA® remote vapor- and
gas-actuated thermometers are
manufactured to the highest standards
for a wide range of uses and can be
fitted into almost any temperatureindicating
instruments are ideal for remote
reading, such as panel installations,
with capillary lengths of 1 to 100'.
Vapor, or more precisely vaporized
liquid, thermometers will give
excellent readings, provided the
temperature being measured is
above or below ambient temperature.
Vapor instruments also have
progressive graduations and are
best read in the upper 2.3 of the dial
range. Many ranges are available
between -40 to 232°C (-40 to 450°F),
and care should be taken to select a
range that will locate the operating
temperatures within the upper 2.3 of
the dial range.
OMEGA gas-actuated thermometers
combine advanced gas coil technology
with a state-of-the-art gas absorbent
(Class IV) thermal system, producing a
superior temperature measurement
instrument that can be fitted to a wide
variety of applications. Gas-actuated
thermometers have an advantage
over vapor-actuated thermometers
in that they are more accurate over the
full range. They also operate at higher
and lower ranges than vapor-actuated
The linear dial on all OMEGA gas
thermometers provides a consistent
1% accuracy across the full span of
each range. This, combined with
over 20 Fahrenheit and dual ranges,
from -196 to 649°C (-320 to 1200°F),
provides complete coverage of all
normal temperature requirements.
