High Corrosion Resistance Sheathed Thermocouple & Thermowell
SUPER COUPLE® 1000M(SC1000M)

HIGH CORROSION RESISTANCE THERMOCOUPLE & THERMOWELL

Features

For sheathed thermocouples used across a wide range of environments, we have adopted a specialized sheath made from a highly corrosion-resistant nickel-based alloy.
This advanced design significantly reduces degradation caused by corrosion, delivering improved durability and an extended service life.

Superior corrosion resistance compared to HASTELLOY® X*
Maximum operating temperature: 800℃; suitable for use in high-temperature corrosive environments.
Drilled thermowells for thermometers are also available.

Specification

● Corrosion Resistance Test Results

Sheathed thermocouples (φ3.2 mm OD) made of SC1000M, HASTELLOY® X, NCF600, and SUS316 were immersed in a 12% boiling dilute hydrochloric acid solution and left for a specified period of time.

Corrosion Resistance Test
All materials except SC1000M completely dissolved*
NCF600 and SUS316 dissolved within 20 hours.

Typical Measurement Locations

Areas in semiconductor manufacturing processes where hydrofluoric acid, gases, or chemical solutions are used.
Chemical plants and other facilities handling highly corrosive fluids.
Environments subject to sulfuric acid dew point corrosion, such as flue gas desulfurization (FGD) systems.
