Photometric Electrodes
Across the Spectrum
Adding to our titration line, these probes are available in 4 different wavelengths from 470 nm to 625 nm. The HI90060X family of photometric probes use the principle of absorbance at a specific wavelength to identify the equivalence point of a titration with the use of a color indicator.
Specialized Construction
A glass construction minimizes chemical compatibility issues. The stainless steel shield within the glass blocks out ambient light and protects against any grounding loop current that may result in progressive damage of the probe.
Made to Fit
With a 12 mm diameter and 120 mm standard insertion length, these photometric electrodes fit easily into electrode holders. These probes have a universal BNC connector that is used as a potentiometric input on Hanna titrators and autosamplers.
Reflective Measurement
Each probe has a LED at a specific wavelength that shines light through the sample and is reflected back by a platinum mirror sealed in the glass. The reflective measurement has a fixed path length and allows for high color sensitivity in a compact design.
Less Maintenance
With the photometric probe there is no fill solution to change in order for it to be compatible with a non-aqueous sample and there is no pH sensor to foul.
For Colorimetric Reactions
The use of a photometric probe for potentiometric titration can be used for a variety of complexometric titrations. The photometric probe is also ideal for non-aqueous titrations.
