Platinum-Rhodium-Single
Fine-Diameter Thermocouple Wire
for High-Temperature Applications
U Types S, R, and B
U Type R and S Temperature
Ranges from
1398 to 1482°C
(2550 to 2700°F)
U Type B is Rated
for Continuous Use
Up to 1704°C (3100°F)
For high resistance to oxidation
and corrosion at high temperatures,
OMEGA offers the highest-quality
uninsulated wire for 3 types of
“noble metal” thermocouples:
Type S: Platinum (–) vs.
Platinum 10% Rhodium (+)
Type R: Platinum (–) vs.
Platinum 13% Rhodium (+)
Type B: Platinum 6% Rhodium (–) vs.
Platinum 30% Rhodium (+)
Types R and S are recommended
for continuous use in oxidizing or
inert atmospheres up to 1398°C
(2550°F) or short-term exposures
to 1482°C (2700°F). Type B is
rated for continuous use up to
1704°C (3100°F) in oxidizing or
inert atmospheres. When operating
near these maximum temperatures,
the heavier-gage wire sizes are
recommended.
All 3 thermocouple types can be
used in a vacuum for short periods.
Type B offers the greatest stability in
such applications. None should be
used in reducing atmospheres or in
atmospheres containing metallic or
non-metallic vapors unless protected
by non-metallic protection tubes.
Do not insert directly into metallic
protection tubes.
Sizes range from 0.025 to 0.812 mm
(0.001 to 0.032") diameter. When
requested, wire is supplied in matched
pairs that meet or exceed standard
limits of error. Special-limits-of-error
wire is supplied on request and must
be ordered as matched pairs.

Ordering Example: Quantity = 100" of SP10R-010, 100" of Type S positive
and 100" of matching Type S negative wire, 0.010 Dia., 100 x 16.00 = $1600.
