Air Products (UK) supply miniature monel bourdon type gauges for corrosive
gas service. I have used these with BrF5 and ClF3. They are cheap (c. 50
pounds sterling) and come with NPT thread or VCR fittings. Pressure ranges
-1 to +1 atmospheres or -1 to +3 atmospheres. Unfortunately I've mislaid
the catalogue so I dont have a contact phone number right now. I'll find it
if anyone is interested.
