662 photometer insert the photometer into the sample not vice versa · glass fiber light guide probe can be used in any vessel · measures absorption or transmission calculates the concentration · supplies the signal for photometric titrations
| convincing features 662 photometer the 662 photometer is a compact microprocessor-controlled instrument that is very versatile and has many applications it has been developed for direct photometric measurements and the photometric endpoint determination of titrations it presents the following advantages · glass fiber light guide measurements can be performed in any sample container be it a beaker a test tube a titrating vessel etc the long flexible light guide is just as convenient to use as a ph electrode its resistance to solvents is excellent · wide wavelength range the whole visible region including white light is available without any gaps there is no restriction to just a few spectral regions · gradual filter thanks to the continuous wavelength scale with stepless adjustment measurements can always be performed at the point of maximum absorption accordingly there is no loss of sensitivity due to non-optimal selection of the wavelength · display of transmission absorption and conc
