Overview
The Omega TT-T-24-SLE thermocouple wire is a duplex-insulated Type T thermocouple wire designed for precision temperature measurement in industrial and laboratory environments. This 100ft spool features a solid 24 AWG conductor with PFA insulation rated for continuous operation from -200°C to 200°C (-328°F to 400°F). The Special Limits of Error (SLE) accuracy specification ensures tighter tolerance measurements compared to standard grade wire, making it ideal for critical temperature monitoring applications where accuracy is essential.
