In colorimetric applications, color is measured objectively; therefore, visual color perception should be simulated precisely as possible with the color measurement systems used. as the result color stimulus. The objective of the measurement is not (physical, spectral) color stimulus, but the (efect-p Calibrate the Colorimeter. Slide the lid of the Colorimeter open to reveal the cuvette slot. Slide the lid of the Colorimeter open to reveal the cuvette slot. Instrument Measurement techniques in colorimetry. The waterproof C/////// Colorimeter allows you to measure up to seven parametersnamely the pH, Cyanuric acid, Free Chlorine, Total Chlorine, Chlorine Dioxide, Bromine and Ozone of a sample and reports the results in appropriate units (ppm or pH) The Hach DR/ Series Colorimeter shown in Figureis a microprocessor-controlled, LED-sourced filter photometer suitable for colorimetric testing in the laboratory or the field. STANDARD OPERATING PROCEDURE FOR COLORIMETERInsert plug in the socketSwitch on the instrument at leastminutes before useEnsure to keep water Press the button on the Colorimeter to select the correct wavelength for your experiment (nm, nm, nm, or nm)Allow the Colorimeter to warm up 4 TABLE OF CONTENTS, continued NITRATE, High Range, Test ‘N Tube,, Chromotropic Acid MethodNITRITE, High Range, Ferrous Sulfate Method Calibration based on standard detectors Introduction The spectral responsivity based calibration method Calibration and measurement considerations Transfer Depending on your testing needs, you can select a DR/, DR/ or DR/ Colorimeter, preprogrammed to test for at leorparameters, respectively Measurement techniques in colorimetry. All three models include the same convenient features: auto-wavelength selection, datalogging capabilities and user-generated calibrations General Information. The instrument is precalibrated for common colorimetric measurements and includes convenient calibration capability for user-entered and future Hach methods. Use of the factory calibration is recommended USE OF COLORIMETER SCALE READING The Klett-Summerson Photoelectric Colorimeter scale is specifically designed to enable the analyst to take full advantage of The spectral and broad-band (illuminance) responsivities of the photometer (Y) channels of two tristimulus meters were determined at both the Spectral Irradiance and Radiance Calibrate the Colorimeter. Insert a cuvette, filled with distilled water or other solvent used to prepare your solutions, for your calibration blank (% transmittance orabsorbance) STANDARD OPERATING PROCEDURE FOR COLORIMETERInsert plug in the socketSwitch on the instrument at leastminutes before useEnsure to keep water blank before switching on the instrumentSet the required wavelengthSelect %T using the knob and adjust to %Switch the knob to O.D which should be zeroClean the 4 TABLE OF CONTENTS, continued NITRATE, High Range, Test ‘N Tube,, Chromotropic Acid MethodNITRITE, High Range, Ferrous Sulfate Method Depending on your testing needs, you can select a DR/, DR/ or DR/ Colorimeter, preprogrammed to test for at leorparameters, respectively.
