Consult sales for units available with Inconel construction
Does the wire come with the thermocouple on the end? if not, what thermocouple end is recommended?
These are purely a Thermocouple cable with no welded junction. The customer can weld and create there own junctions as needed or look at the BLMI series as an alternative.
Date published: 2021-03-04
How long is the wire? (or, what is the price per unit length?)
The cable assembly is sold per meter. Cost is listed above.

How can I stripper the sheath to expose the thermocouple wire to a junction and make the connection at the other end? I have got the 0.25 mm OD wire
Thank you for your inquiry. We use a small spot welder with larger copper contacts that will "FLASH STRIP" the sheathing and not damage the wires so a junction can be made.

Does this come with the brass end to lock into thermocouple?
Thanks for your inquiry. This item does not come with the thermocouple but is sold separately. Please see the attached link for the fitting. https://www.omega.com/en-us/valves-pumps-and-mixers/pipe-and-tube-fittings/p/MTA-BRLK-SSLK-RA-RB

Is this wire considered thermocouple grade or extension grade? The T type temperature range is generally considered to be -240c to 300c, is there a reason that this temperature rating starts at 0?
Thank you for connecting with Omega.
Part number 304-T-MO-3.0MM is thermocouple grade and made with standard limit of error wire.
This wire will measure temperatures down to -200 deg C.
The accuracy is the greater of +/- 1.0 deg C or 0.75% of reading for temperatures between 0 and 315 deg C.
For temperatures between -200 and 0 deg C the accuracy is the greater of +/- 1.0 deg C or 1.5% of reading.
