Product Details
0.5mm S type Platinum Rhodium Thermocouple Bare Wire
Factory directly supply Type K thermocouple bare wire
We offer 0.3mm/0.4mm/0.5mm B/R/S type Platinum Rhodium Thermocouple
Bare Wire that can be availed in different sizes as per the
requirements of the clients.We offer Bare Thermocouple Wires that can be availed in different
diameter and length as per the requirements of the clients. They
are always supplied in pair and calibrated. The Platinum Rhodium
Thermocouple Wires that we deal in are used in varied applications
related to the measurement of high temperature.
1)Type B (Platinum / Rhodium)
Suited for high temperature measurements up to 1800 °C. Unusually
type B thermocouples (due to the shape of their temperature /
voltage curve) give the same output at 0 °C and 42 °C. This makes
them useless below 50 °C.
2)Type R (Platinum / Rhodium)
Suited for high temperature measurements up to 1600 °C. Low
sensitivity (10 µV/ °C ) and high cost makes them unsuitable for
general purpose use.
3)Type S (Platinum / Rhodium)
Suited for high temperature measurements up to 1600 °C. Low
sensitivity (10 µV/ °C ) and cost makes them unsuitable for general
purpose use. Due to its high stability type S is used as the
standard of calibration for the melting point of gold (1064.43°C).

Company Profile
Changzhou DLX Alloy Co., Ltd. was established in 2002 and has
passed ISO9001 international quality management system
certification and SGS certification.We initially focused on the
production of resistance alloys. Over the past 20 years, we have
continued to conduct research and development and now offer a range
of alloy products, including Inconel, Monel, Hastelloy,
high-temperature alloys, and other nickel-based alloys. Our
commitment to meeting the needs of industries that require high
strength, strong corrosion resistance, and high-temperature
performance is reflected in our focus on developing these alloys.
