    The thickness of the water layer is proportional to the density (concentration) of the turbid particles present in the water. The light used in TW-150 has a wavelength of 870 nm, and is compliant to ISO 7027-1:2016. Color Measurement The transmitted light measurement method is used in TW-150. This method measures the level of brownish-yellow in yellow-like colors shown in dissolution and colloidal materials contained in water at a wavelength of 375 nm using absorptiometry.

    9 REFERENCE Electrode cleaning  This system adopts bead cleaning to maintain the electrode surface and measurement stable. pH Measurement pH measurement and temperature  The temperature of the solution being inspected is an important parameter in the accurate measurement of pH. There are many possible sources of errors during measurement, such as the state of the solution junction potential, asymmetric potential, and standard solution pH concentration, but all of these items contain factors that change with the temperature.

  • Page 195: Conductivity Measurement (Optional)

    9 REFERENCE Types of pH standard solutions  When measuring pH, the meter must be calibrated using a standard solution. There are several kinds of standard solutions. For normal measurement, two standard solutions (with a pH of 7 and 9) are sufficient to accurately calibrate the meter. pH 1.68 standard solution: Oxalate 0.05 mol/L tetra-potassium oxalate aqueous solution pH 4.00 standard solution: Phthalate...

    9 REFERENCE Each positive and negative ion in the solution will migrate toward the oppositely charged pole. The result is that current flows through the solution by means of ion conductivity. When this occurs, resistance R(expressed in ), is in inverse proportion to the area A (expressed in m of the pole plates, as is the case with metal and other conductors, and is proportional to the distance l (expressed in m) between the two pole plates.
