thermocouple wire1Non-insulated fine diameter, single wire and pair
wire, ultra-high temperature resistant2Types S, R and B3R-type and
S-type temperature range 1398 ~ 1482°C (2550 ~ 2700°F)4Type B is
suitable for continuous use at temperatures up to 1704°C
(3100°F)5To effectively prevent oxidation and corrosion at high
temperatures, OMEGA offers high-quality uninsulated thermometer
wires that can be applied to 3 types of "precious metal"
thermocouples: Type S: Platinum (-) and Platinum 10% Rhodium
(+) Type R: Platinum (-) and Platinum 13% Rhodium
(+) Type B: Platinum 6% Rhodium (-) and Platinum 30% Rhodium
(+)9Types R and S are recommended for continuous use in oxidizing
or inert atmospheres at temperatures up to 1398°C (2550°F), or
short-term exposure to high temperatures up to 1482°C (2700°F).
Type B is suitable for continuous use in oxidizing or inert
atmospheres up to 1704°C (3100°F). When working close to the
maximum temperature, it is recommended to use a larger wire
diameter.10All 3 types of thermocouples can be used in a vacuum
environment for short periods of time. Type B provides the best
stability when applied in a vacuum environment. All 3 models are
not suitable for use in reducing gases or environments containing
metallic or non-metallic vapors unless a non-metallic protective
sleeve is used. Never insert thermocouples directly into metal
protective sleeves.11Wire diameters range from 0.025 to 0.812 mm
(0.001 to 0.032"). If desired, thermocouple wires can be supplied
in pairs that meet or exceed standard error limits. Special error
limit wires are available on request and must be paired
order. Materialmelting pointResistivityPure

manufacture. PtPh10/Pt thermocouple is the most accurate
thermocouple for temperature measurement above 300°C, and it is
also the international temperature benchmark in the range of
630.74~1064.43°C. Generally, the temperature can reach 1350°C
(short-term 1600°C) PtPh30/PtPh6.PtPh13/Pt.PtPh20 /PtPh5.
Thermocouples such as PtPh40/PtPh20 can measure higher
temperatures.In the glass industry, it is used to make
heat-resistant and corrosion-resistant devices such as crucibles,
drain plates, stirrers and electrodes.It is used as a catalyst in
ammonia oxidation and many other reactions.It can be used as a high
temperature heating element. The furnace with PtPh40 alloy as the
heating element can work up to 1800 ºC in an oxidizing
atmosphere.Company ProfileOver the years, we have worked hard to
promote
