Description: | Chem 30. (transfer list number in white paint). oCELS (on scale meaning degrees Celcius). 87 stamped into wood inside instrument casing. 87 679 (written in pencil on the tin plate inside the instrument casing). 1 degree = 0,0001 volt 359 ohm (stamped in brass plate between the terminals). 70679 (serial number stamped in the wooden outer casing and picked out in white). SH(makers logo on badly damaged paper labels on the underside of the instrument. DES after ARSONVAL,Jacques-Arsene,d'. 1882 Paris France. MANU Siemens & Halske. circa 1900 Berlin, Germany. DES after SCHWEIGGER,Johann,Salomo,Christoph. 1820 Halle, Germany. DES after STURGEON,William. 1836 Adelaide Gallery of Practical Sciences, 7 Adel This instrument is a dual purpose mirror and pointer galvanometer with two scales one from 0-180 the other from 0-1600, presumably so that the instrument could be used as a temperature measuring device when connected across a thermocouple or resistor. CHEM 1 photograph list records the instrument as a pyrometer which ties in with the above.
The instrument was possibly designed to work in conjuction with a Fery radiation pyrometer which used a concave mirror to focus the heat from a furnace or other hot body onto the thermocouple or thermopile. | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | SCIENTIFIC COLLECTION : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
