probe obs300 in lab with standard

kokihualpa Jun 14, 2017 05:23 PM

dear friend

We probe the sensor of turbidity in a glass of 120 ml of 100 NTU and 800 NTU (standards).

but the sensor measure: 100 NTU= 250-500 NTU(obs300)

800 NTU= 910-940 NTU(obs300).

with the program created by shortcut.

but why there is that differences?.

You are probably getting reflections from your container.

You should be using a black plastic container to reduce reflections.
