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 = -log10 T
T = I / I0
where:
T = transmission in %
I = current light intensity
I0 = 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 SACxxx and Axxx. 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 (A740) 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:
SACXXX = (Axxx – A740) * 1000 / d
where:
d = length of the optical path of the sensor in mm
SAC = spectral absorption coefficient in 1/m

Installation
CAUTION
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
Installation guidelines
Note: Make sure that the enclosure of the probe is titanium before use in sea water.
• Do not use stainless steel probes in sea water or other corrosion-causing media (e.g., acids,
alkalis, chlorine-based compounds). Clean the probe immediately.
• Do not use titanium probes in bromine, hydrofluoric acid and hot acids. Clean the probe
immediately if the probe touches hydrofluoric acid or hot acids.
• The seals of the probe are made of NBR (nitrile butadiene rubber). Make sure that the measuring
medium does not cause damage to the probe components.
• Do not replace the cable. If the cable has damage, contact the manufacturer.
• Make sure that the cable is not routed near hot surfaces. Make sure not to put heavy objects on
the cable.
• Make sure that there are no unwanted materials in the optical path.
4In some applications it is necessary to enter a factor to scale the SAC at a specified
wavelength.
8 English
• Immediately set the instrument to OFF if the probe sends out smoke, noxious fumes or gets hot.
Contact the manufacturer.
Installation overview
Figure 3 shows an example of the probe installation with a chain holder option. Figure 4 shows an
example of the probe installation with a flow cell option. Refer to the installation documentation to
install the probe.
Put the probe into the sample. Make sure that the optical path is always fully immersed into the
sample. Install the probe transversally to the flow direction of the sample so the particle on the
windows are at a minimum and the nano-layer function gives the optimum support. Refer to Figure 5.
Note: Make sure that the probe does not touch the ground.

Connect the probe to the controller
N O T I C E
Never connect the sensor to the controller when the controller is energized or damage to the sensor can
occur.
The probe has a 10 m fixed cable with an M12 industrial plug that connects to a digital controller for
signal transmission and power. Refer to Figure 6 and Figure 7.
