73. ts are specific to a refractive transducer The last two digits are used to differentiate the probes that may be used simultaneously on the same conditioner It is important for each probe connected to the same conditioner to be distinguishable since the physical cavity lengths are saved in the memory location that corresponds to the zero of the probe Using the same last two digits would force the probes to use the same physical length and thus inaccurate measurements will occur It is important to note that the refractive index measured by the system is not for one single wavelength as it is usually reported in the literature but is the refractive index averaged over the wavelength covered by the internal light source The light source extends from 650nm to 1000nm As a rule of thumb it is generally acceptable to consider that the refractive index is measured for a central wavelength of 800nm 52
