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.
