    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.

      Very Nice, and brings back memories for me. These were most often installed in a threaded well, that was welded to the chilled, and heating water supply pipe and return lines, in commercial heating and cooling systems. To check calibration, stick probe in ice water, and slide scale to 32 degrees if need be. Yours could have been used in either cooling H20, which normally runs at 45 degrees, or heating H20 at 180, to 200 degrees F.
