Just FYI (for your information), if you mean it's 23C with a bit of
variation, the convention amongst American English speakers would
be "23 C, +/-" where the '+/-' is understood to mean "by not enough to
make that much difference."

The OCXO is in test, in these room tempearture ,
but the housing of the OCXO (type MV89A) in the room temp ( 23 C)
is about 60 C -- and ' very hot ' to hold in the hand....

Maybe it's supposed to be that way, and you're not supposed to hold it in
your hand while it's in operation. It is an "oven" after all. What does the
owner/operator manual say?

Another popular American colloquialism is, "When all else fails, read the
instructions." ;-D

Cheers!
