(170)
Transmission
0.0 - 100.0 % (Trnsm)
Internal Name: 170-Transmission
10ml
Measurement procedure:
1 Select the desired wavelength.
2 Fill 10 ml test water into a clean 24 mm cuvette.
3 Screw the lid back on the cuvette.
4 Insert the cuvette into the PrimeLab. Pay attention to the arrow on the front of the cuvette.
5 Start ZERO measurement.
6 Remove the cuvette again.
7 Treat the water sample according to the chosen procedure.
8 Fill 10 ml of the treated water sample into a clean 24 mm cuvette.
9 Screw the lid back on the cuvette.
10 Insert the cuvette into the PrimeLab. Pay attention to the arrow on the front of the cuvette.
11 Tap TEST to perform the measurement.
12 The measured value is immediately displayed.
Notes:
With this method you can create your own parameters, use reagents from other manufacturers
and/or perform measurements with the PrimeLab that are not included in the offered IDs/
parameters.This requires that you familiarize yourself with the colorimetry of the water sample
AFTER addition of the reagent that you want to use. Select the wavelength of your sample after
addition of the reagent to be used by selecting the closest colour match (see also
www.primelab.org).At the end of measurement you will receive a value for the "Transmission".
"Transmission" in % means how much light reaches the sensor (in %), compared to ZERO
measurement (T = 100%). After adding a colouring reagent, transmission will decrease.Simply
measure several water samples with different concentrations of the parameter of interest on one
wavelength, to record your own values using the determined transmission results.
