The optical path on the NICO can be modified by the end user from 0.3 mm, to 1 mm, 2 mm, 5 mm or 10 mm. The optical path size determines the range and the accuracy of the sensor.
Optical Path SizeRange Accuracy in (mm): (NO3-N) ; (NO3) / (NO3-N) ; (NO3)
- 0.3mm: (0-200) ; (0-886) / ± (5% of the reading + 3.3) ; (5% of the reading + 14.5)
- 1mm: (0-60) ; (0-266) / ± (5% of the reading + 1.0) ; (5% of the reading + 4.4)
