The Type E has a stronger signal & higher accuracy than the Type K or Type J at moderate temperature ranges of 1,000F and lower. The type E is also more stable than the type K, which adds to its accuracy.
Type E Temperature Range:
Thermocouple grade wire, -454 to 1600F (-270 to 870C)
Extension wire, 32 to 392F (0 to 200C)
Type E Accuracy (whichever is greater):
Standard: +/- 1.7C or +/- 0.5%
Special Limits of Error: +/- 1.0C or 0.4%
Consideration for bare wire type E thermocouple applications:
In oxiding or inert atmospheres the operating range is roughly –418F to 1,652F (–250C to 900C).
