Here's another old industrial thermometer I came across again the other day laying in a drawer. Unlike my other (recent thrift-store find) one of these, I've had this one since the mid 1980's or so, it having been recovered by a friend of mine working at the time on a 'scrapping crew' during the demolition of a Pabst Blue Ribbon brewery in Peoria, IL.
This one is made by PALMER (now "Palmer Wahl Instrumentation Group") and its face is 2-1/4" x 10", with a range of 30 - 240 degrees Farenheit. The words "PALMER CIN. O. U.S.A." also appear screened onto its temerature scale, at the very top LH side. (mostly obscured behind the chrome top piece, when viewing straight-on)
Like my other, this would have been intended to thread into a fitting on a pipeline or tank or something, to ultimately display the temperature of liquid within.
