  • Never miss a measurement with stored logging.
  • GLP (Good Laboratory Practice) function for calibration traceability.
  • Specially designed for water quality measurements.

Significance of Use Jual Turbidity Meter HANNA HI98703-01 :

Turbidity is one of the most important parameters used to determine the quality of drinking water. Once considered as a mostly aesthetic characteristic of drinking water, signi˜ficant evidence exists that controlling turbidity is a competent safeguard against pathogens. In natural water, turbidity measurements are taken to gauge general water quality and its compatibility in applications involving aquatic organisms. The monitoring and treatment or wastewater was once solely based on the control of turbidity. Currently, the measurement of turbidity at the end of the wastewater treatment process is necessary to verify that the values are within regulatory standards.

Turbidity of water is an optical property that causes light to be scattered and absorbed, rather than transmitted. The scattering of light that passes through a liquid is primarily caused by the suspended solids present. The higher the turbidity, the greater the amount of scattered light. Even a very pure liquid will scatter light to a certain degree, as no solution will have zero turbidity.

Drinking water treatment plants that obtain water from surface water are required by the EPA to monitor and report the turbidity. Surface water sources include lakes and rivers.  The requirements of the nephelometer and reporting measurements according to  EPA Method 180.1 are:

  • The applicable range is 0-40 nephelometric turbidity units (NTU)
  • Light source:  Tungsten lamp operated at a color temperature between 2200-3000°K.
  • Distance traversed by incident light and scattered light within the sample tube: Total not to exceed 10 cm.
  • Detector: Centered at 90° to the incident light path and not to exceed ±30° from 90°. The detector, and filter system if used, shall have a spectral peak response between 400 nm and 600 nm
  • The sensitivity of the instrument should permit detection of a turbidity difference of 0.02 NTU or less in waters having turbidities less than 1 unit.
  • Report results as follows:
NTU readingRounded to nearest
0.0 – 1.00.05
1 – 100.1
10 – 401
40 – 1005
100 – 40010
