Product overview
The NV3300 color probe is a photometric sensor used for Spectral Absorption Coefficient (SAC) or
transmission measurements in aqueous solutions in waste water, drinking water and environmental
applications. Refer to Figure 1.
There are 8 different models of the probe based on the application and the measured parameter.
Each model has different parameters based on the nominal wavelength of the LED. The probe is
available with 4 different optical path lengths: 50, 100, 150 and 250 mm. Refer to Specifications
on page 3.
The probe connects to a CD500 or a CD300 digital controller to monitor the measurement data,
calibration and configuration.

Theory of operation
The sensor uses two LEDs for long-term stable measurements of SAC values or color numbers at a
different wavelengths. Table 2 shows the applicable parameters based on the sensor type.
The light intensity of the LEDs usually changes with the temperature. The sensor uses a correction
factor for each different wavelength to calculate the measurement value. The absorbance is
calculated with the formula that follows:
A = -log
10
T
T = I / I
0
where:
T = transmission in %
I = current light intensity
I
0
= basic light intensity in ultra-pure water
A = absorption in AUs (absorbance units)
Based on the model, the sensor outputs the SAC (Spectral Absorption Coefficient) of the wavelength
of LED1. The wavelength and absorption of LED1 is labelled in the sub-index SAC
xxx
and A
xxx
. The
wavelength of LED2 is 740 nm. The scattering of light on particles in a solution is seen as turbidity.
The sensor uses the absorbance of 740 nm (A
740
) for the turbidity correction of the absorption
measurement of the wavelength emitted by LED1. The SAC of each wavelength of LED1 is
calculated with the formula that follows:
SAC
XXX
= (A
xxx
– A
740
) * 1000 / d
where:
d = length of the optical path of the sensor in mm
SAC = spectral absorption coefficient in 1/m
