Using Check Standards
Why is Percentage Transmission of Light being measured
with Lumiso Check Standards?
Lumiso works by measuring the amount of light that passes
through the sample. This value is known as the “Percentage
Transmission” or “%T”. Lumiso’s software then converts this
%T value into a concentration, such as mg/L of chlorine.
So, to verify that the instrument is within calibration it is only
necessary to check that the instrument correctly measures
%T for each wavelength of light it uses. This simplifies the
process for using check standards.
Check Standards can be purchased separately for your
Lumiso instrument. These standards contain Neutral
Density Filters (NDFs) and can be used to verify that the
instrument is within calibration
and performing correctly.
