Replacement temp probe for muti-meter

maybe I haven't looked hard enough but I only see the type with the flat blades.

Mine looks like this

Is that an Extech? I thing they have type K therm0couples

I don't have one

It's from harbor freight but I see it's a clone of a few that look the same.. I was just going to say looking at the meter here I could get the fluke adapter that can use a K-type thermocouple assuming the spacing is the same and all.

This one has seen better days... I guess the last time it got up to 1,600F was it's last time it still kinda works but in free air it will sometimes go like -125 F or 100F, I needed it to check how hot the water is (showing 136F)

The one I have

From the manual:

quote:
Plug the red end of the �€˜K type thermocouple into the
TEMP jack and black end into the COM jack. Touch
the surface of the object or area with the temperature
sensor for measurement.
Normally TC connectors have special construction specific to the type of thermocouple. But a lot of the Chinese meters use banana plugs, I assume the cold compensation is physically connected to the input jacks.

Lots of them on ebay:

I thought the big box stores have them. I know my local Sears does.

I haven't been in sears in awhile so not sure..

I have a question I need to monitor the temp of a wheel that will have heat blowing on it, the heat will be on the front side and the temp probe on the backside, is epoxy enough to keep it on and keep the temp stable to get a good reading?

I need to do at least 400-410F for about 15 min

I would be leery of normal epoxy at that temp , most are only rated for 350-400 F , and are not the worlds best heat conductors .
For some reason JB weld is rated to 550 , and since it is metal filled " should " conduct heat better .

Any reason you can't use an IR thermometer ? Granted it would not be as accurate , but much easier .
When we had to take accurate temp readings of metal ( non molten ) , we would normally try for a solid mechanical connection of some kind . Bolted on , in a drilled well , soldered on ,etc .

Something I noticed when looking through the manual for that multimeter... how the hell is it rated for CAT III 600V with only a 10A 250V fuse for protection?

Well I don't need it to be on the wheel long.. I need it for like 20-30 min and I need it to come off with somewhat ease, I have a IR thermometer but won't air currents between me and the part throw the reading off?

I just remembered I have high temp tape too.

"I have a IR thermometer but won't air currents between me and the part throw the reading off?"
Not really . You are measuring the IR waves given of by the object that you are measuring . Unless you have something solid between the object and the thermometer the waves are not stopped at normal measurement ranges .That is the reason you cannot take IR readings through glass , or my personal favorite , a new tech trying to read the temp of a submerged element through a liquid .
Think what I am trying to say is that a IR thermometer will read the temp of the first non air surface it sees .
As long as the air is not filled with particulates , the motion of the air will not matter .
Just remember that 10% accuracy is probably as good as you are going to get with an IR thermometer .

If you use the HT tape to hold the sensor in place , you may want to use some thermal compound , or a piece of metal foil , to ensure that all sides of the thermocouple junction see the same temp . Just holding the junction down with tape could , and I expect would , lead to a low reading .

I would recommend using Loctite 384 thermal adhesive.

it's harbor freight. everything's underengineered LOL

Anyone would be stupid to use it on anything that high anyways, for something like that I'd look for something higher rated..

Besides highest I've never checked was 240 VAC and 480 VDC

Don't worry that fuse isn't even in the path of any voltage measurements

The fuse is only on the current sensing input.
