I am searching for Dowsil 710 or a suitable replacement oil to be used in a 200 degree C bath. I'm finding a 27 week lead time as the government has bought up all supplies, as far as we can tell. This is used in a bath for calibrating RTD's. Any suggestions?
Julabo makes several high temp oils. Also Fluke has their 200.20 silicon oil.
