If you just need temperature I would recommend the Oregon MTR102 - no cables

And horribly inaccurate.

Personally, I've found that the quoted accuracy of +/- 1°C is about
right. Close enough for enthusiastic amateurs like myself (though I
don't use one for the monthly records I post here).

Personally I've found that any two of these units can disagree by 2 degrees
so I concur with you about the high level of inaccuracy

I am quite sure that with one of these Oregon devices, you never know the
temperature. With two, you don't know the temperature twice.

Maybe I was just lucky with my remote sensor then?

Given the huge variation in accuracy of these Oregon devices, there's bound
to be the odd one that is acceptably accurate. Trouble is, which one?

Do bear in mind that the Met Office accurracy is only 0.5C, how ever
last time I looked on the Met O site it didn't say if that was:

a) +/- 0.5C
b) + 0.5C, - 0.0C
c) + 0.0C, - 0.5C
d) +/- 0.25C

The last slightly contradicts the resolution of 0.1C as the
specification for the accuracy requires higher resolution than
required resolution...

Dave,

Met Office liquid in glass thermometers are accurate to 0.2C (+/- 0.1C)
