K. H. Weigand Messtechnik GmbH was a maker of selenium light meters in Erlangen, Germany. The company was founded as Weigand & Ehemann shortly before the Second World War.[1]

Accessories importer Actina distributed some Weigan products in the UK.[2]

Weigand registered a number of patents for electrical devices such as innovative features of moving-coil meters.[3] From about 1960, these begin to refer to general measuring instruments rather than specifically to light meters. This may have reflected the decline in the use of selenium meters in favour of other sensors, or a desire to diversify. The company was closed in 1984.[4]


Lightmeters

  • Actino, 1948
  • Actino A, 1949
  • Super Actino
  • Actophot U
  • Actino S


Notes

  1. ↑ Actino A with brief statement about the company, at lightmetermuseum.com ('Annsi's Collection')
  2. ↑ An advertisement by Actina from the 1957 British Journal Almanac, reproduced in the listing for Actina at Grace's Guide includes a photograph of an Actino S. Curiously, the advertisement names it the Actinos (a common error noted by 'Annsi' at his website), and the unit pictured carries the name Actophot.
  3. ↑ Weigand patents archived at Espacenet, the patent search facility of the European Patent Office.
  4. ↑ The listing for Weigand Messtechnik at Alexander Kusdas' Sammlung historiche Messtechnik, Berlin (Collection of Historical Measuring Instruments; a private collection) states that Weigand was removed from the company register on 1 February 1984.
