TT-J-24-1000 : OMEGA Thermocouple Wire

The OMEGA TT-J-24-1000 is a high-performance, duplex-insulated Type J thermocouple grade wire designed for reliable temperature measurement across industrial, laboratory, and OEM processing applications. Featuring premium PFA (Perfluoroalkoxy) insulation over solid 24 AWG conductors, this wire delivers exceptional resistance to moisture, chemicals, and mechanical wear over a temperature range of -210°C to 260°C. Supplied on a 1,000 ft (304.8 m) spool, it is an ideal choice for constructing custom Type J sensors or running long extension lines.

Key Features

• Type J Calibration: Manufactured with genuine Iron (Positive) and Constantan (Negative) conductors for reliable accuracy in reducing atmospheres and vacuum environments.

• High-Performance PFA Insulation: Provides outstanding dielectric strength, chemical inertness, moisture resistance, and low friction.

• Broad Temperature Range: Suitable for continuous operation from sub-zero temperatures (-210°C) up to 260°C.

• ANSI Color Coded: Complies with standard ANSI color coding for quick identification—White for Positive (+), Red for Negative (-), and Brown overall jacket.

• Solid 24 AWG Conductor: 24 AWG solid wire provides excellent structural integrity, stability, and ease of connection.
