Replacement Thermocouple for EEV BM235

[CarnivalBen]

I bought an EEV blog Brymen BM235 multimeter, but stupidly damaged the thermocouple.

I bought a replacement from eBay but it’s not as good as the original, doesn’t seem to be as acurate, and the banana plugs are not that good.

Does anyone know where I can buy a replacement k type thermocouple that is identical to the one you get with the multimeter?

Perhaps the   +  and   -  on the replacement thermocouple are reversed or miss-labelled?    

I find for average use there isn't a lot of difference between the thermocouple thingies supplied with multimeters and the cheap generics sold at electronics stores

FWIW, I had a few on the bench a while back, Fluke, Brymen, Mastech and others compared with a few cheapies from Jaycar Electronics,

all immersed in the same container of boiled hot water, and the readings checked as the water cooled

I swapped them about at random amongst the meters, and the worst case difference may have been 1 or 2 degrees Celsius,

which may have been meter differences too rather than just the thermocouples 

At various points they were all pretty much in agreement, give or take .05

so I stopped there and packed the lot away to get the kitchen table back to normal duties 


Anyway it was just a rough go / no go / curiosity  test to decide if any are 'better' or more accurate etc and take a note for future reference   

and not blow unnecessary dollars  again   


You may have scored a dud thermocouple with a break somewhere from the tip to the banana connectors, it happens
