Which do you think is correct based on where the vial is held in relation to the white background. One is an inch or so, another half that and last right on it as the photos depict using the same sample.
The instructions should tell you how to view it. Some tests you look down from the top, others should be held away from the card, other still on the card.
I am displaying the correct way you would view the result. The Salifert version I have goes through the side. My question was more or less where anyone felt the result looked closest to.
That's a big window about a foot to the left providing the light. Oh well I suppose I'll just wait for the Hannah to get here then.
Thanks... everyone.
