121GW included thermocouple maximum operating temperature?
« on: August 23, 2018, 01:23:13 am »
I'm wondering what temperature I can safely operate the included thermocouple at? The 121GW manual states that it can measure up to 1350 degrees C, but I think that's talking about the range the multimeter is capable of understanding, not the temperature that the specific supplied thermocouple's insulating sleeve can withstand.

Does anyone know what the model number and/or operating temperature range of the supplied thermocouple is?

Usually they are K type. Check for a K on the connector.

Edit: Yes, K type, it says in the manual. And yes, K type can withstand 1350C.

Maybe the thermocouple metal itself, but I doubt the insulator around it can stand up to that.

I contacted Kane and they said it will measure up to 1350 degrees.

Wow, really? Are you sure they're not making the same mistake as Miti? What is the insulation made of, glass fibre?

Organic insulation won't even come close to surviving 1350 °C. Mineral Insulation.

Seppy, can you please go back to the manufacturer? I simply cannot believe the insulation on this thrown-in-the-box thermocouple has a higher thermal tolerance than even the most exotic materials listed here: https://en.wikipedia.org/wiki/Thermocouple#Table_of_insulation_materials

Done, we will see... I agree, I don't know how that is a thing, I've asked what the insulation is.
