1000ft spools not sturdy enough for shipping
Lately every time I order a 1000ft spool it is cracked in have when I receive it. I try to order only 500ft spools for this reason.

Good Wire
This is very good wire. The one thing I would change is making the insulation on the red conductor more visible. It looks too clear.

Solid Thermo Wire
Bought for industrial purposes, works great. Stripping can be messy as it is cloth insulation.

What is IEC standard
Thank you for your interest in our Product
.
IEC will apply to the color coding of the jacket and insulation only. For Thermocouple Grade Type J for example, the color coding is a Black jacket with a (+) Black and (-) white insulation
All accuracy testing of the wire is conducted in accordance with ASTM E 230 which has slightly tighter tolerances in the lower temperature ranges than the IEC 584 specification.

Does this come with the connectors to attach to the meter?
Thank you for your inquiry laz87. No, this wire does not come with the connectors. The connectors are sold separately.
