  • Page 6: Background Information

    BACKGROUND INFORMATION Introduction to Colorimetric Measurement Palintest methods are based on measuring the intensity of colours produced by Palintest reagents and using Palintest photometers to measure that intensity of colour. This method is called colorimetry and can be defined as any technique used to evaluate an unknown colour in reference to known colours.

  • Page 7: Blanks And Samples

    Blanks and Samples Palintest photometers use a BLANK tube to set the instrument to blank and a SAMPLE tube to take the reading. A BLANK tube is a test tube filled with untreated water sample. A SAMPLE tube is a test tube containing the sample to which reagents have been added in accordance with the test procedure described.

  • Page 36: Troubleshooting

    Note: it is not possible to dilute samples in the pH test, or when working in transmittance. It is very important to specify Palintest Photometer Grade tablets when ordering replacement reagents for this instrument. Using an alternative grade of tablet may lead to a turbid sample which in turn...

  • Page 37: Chlorine

    Unwary pool operators may add further shock dose at this point, and this further raises the false total chlorine result. Palintest’s DPD Oxystop has been developed to prevent this problem. The DPD Oxystop tablet should be added after the DPD No 1 Free Chlorine test result has been read and before the DPD No 3 tablet is added.

  • Page 38: Alkalinity

    The range of the cyanuric acid (CNA) test is 2 - 200 mg/l. Higher levels can be tested by first diluting the sample with mains or deionised water and then applying the appropriate dilution factor. Palintest’s Dilution Tube (PT 512), which is available as an optional extra, should be used for the...

  • Page 39: Calcium Hardness

    Calcium Hardness The expression of hardness results sometimes causes confusion. It is normal practice to express the results of hardness tests as mg/l CaCO (calcium carbonate). This is merely a convention to allow the comparison of different results and does not necessarily indicate that the hardness is present in the water in this form.
