HI731318 are microfiber cloths for wiping the cuvettes used in Checker HC (HI700 series) handheld colorimeters, photometers (HI96000 portable series and HI83000 benchtop series) and turbidity meters. These cloths remove dirt, grease and fingerprints from the vials so that the glass is clean for the unimpeded transmission of light.
· Lint free
· Will not scratch glass cuvettes
Using cuvettes in photometers, colorimeters, and turbidity meters that are clean and free from scratches is critical in order to obtain an accurate measurement. These systems are optically based in which light must transmit through the glass vial in order to be detected by a silicon photodetector. Any impedance in the light path will affect the way that light will interact with the sample to be measured ultimately affecting the result obtained from the meter. Using clean HI731318 microfiber cloths will not scratch the cuvettes which can interfere with the optical system.
Example of optical systems used in photometers and turbidity meters
Photometer optical system (HI96 series)
ISO turbidity optical system (HI98713, HI88713)
Tungsten lamp (EPA) optical system with 90o and 180o scattered light detectors along with a built-in photometer (HI93414, HI83414)
