Specifications - Honeywell C7046C Product Data

SPECIFICATIONS

IMPORTANT
The specifications given in this publication do not
include normal manufacturing tolerances. Therefore,
these units may not exactly match the specifications
listed. Also, these products are tested and calibrated
under closely controlled conditions and some minor
differences in performance can be expected if these
conditions are changed.
Models:
Specifications for each model are listed separately.
