FOREWORD

HF TURBIDIMETERS

HF turbidimeters are manufactured to meet design criteria for nephelometers as described in Standard Methods For
Examination of Water and Wastewater. HF turbidimeters are approved by the U.S. EPA* as a means to measure the
turbidity of potable water, waste water, and other liquids.

HF turbidimeters provide a linear display of turbidity, throughout all ranges, in Nephelometric Turbidity Units (NTU).
HF turbidimeters use solid state electronic components because they resist thermal variation and are not affected by
normal line voltage fluctuations.

HF turbidimeters can be calibrated using HF scientific factory certified Secondary Standards or Formazin. Factory
calibration is accomplished using HF scientific Secondary Standards, which are factory certified traceable to
Formazin, therefore, this instruction manual describes the proper procedures for calibration of HF turbidimeters using
Secondary Standards.

HF turbidimeter manuals are designed to assist the user in taking full advantage of the instrument in a majority of its
applications. However, in the event that unusual circumstances or problems, not covered by this manual, arise please
feel free to contact our local distributor or the manufacturer.
