Lumiso works like other photometers, by measuring the amount of light that passes through the sample in comparison to the blank. This is known as the “Percentage Transmission” or “%T”. This %T value is mathematically converted by the software to a mg/L concentration.
Therefore, to verify that the instrument is performing within calibration it is only necessary to check that the instrument measures correct values of %T at each wavelength of light it uses. If the instrument is reading the %T value correctly according to the certificate, the correct mg/L value will be displayed when testing.
