HF scientific DRT-15CE Portable Turbidimeter - Manual (Page 5)

DRT-15CE (5/10)
FOREWORD
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 ProCal Standards or Formazin. Factory calibration is accomplished
using HF scientific ProCal Standards, which are factory certified traceable to
formazin, therefore, this instruction manual describes the proper procedures
for calibration of HF turbidimeters using ProCal Standards.
HF turbidimeters use Formazin as the primary standard for
calibration. Therefore, this instruction manual describes the proper
procedures for calibration of HF turbidimeters using Formazin 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.
