Cabinets:
With the mechanical design of all B & K apparatus, it is very easy to inter -
c
hange the instruments with the various cabinets. The equiments are de-
livered in metal cases as standard fittings which can be mounted in any
desired way i.e. - mahogany cabinet or frame for 19
11
standard rack.
Type 1022 A.
The B.F.O. is in a me tal case and is intended for laboratory use.
Type 1022 B.
Similar to Type 1022 A but the instrument and the metal case are housed in
a mahogany cabinet with cover. In this cabinet it is easy to transport the
instrument.
Type 1022 C.
Similar to Type 1022 A, but it is supplied in a frame ready for mounting
the instrument in a 19" standard rack. The in s trument is delivered together
with a chain wheel which can be coupled with the chain drive supplied with
2305 C. ( The LeYcl Recorder used for 19" s tandard rack mounting ).
