Introduction
The Spec Filter test set is designed for periodic monitoring of spectrophotometers. This
instruction sheet includes a template for recording test results. See the Test record template
on page 4.
Transfer the nominal values given in the quality control certificate HDQ178 to the test record.
Make an appropriate number of copies. When results exceed allowable tolerances, contact a
Hach representative.
Electrical equipment marked with this symbol may not be disposed of in European public disposal systems after 12
August of 2005. In conformity with European local and national regulations (EU Directive 2002/96/EC), European
electrical equipment users must now return old or end-of life equipment to the Producer for disposal at no charge to
the user.
Note: For return for recycling, please contact the equipment producer or supplier for instructions on how to return
end-of-life equipment, producer-supplied electrical accessories, and all auxiliary items for proper disposal.
