    These are brand new. The units for sale have been slightly used. They work perfectly. I have measured down to LN2 temperature (-196 C) with these, so the temperature range above is for the wire insulation.
    Unfortunately, they are not compatible in a vacuum chamber, which is where I do my measurements. So I had to replace these with custom thermocouples.
