JKI    JK-FP6400 Flame Photometer

Wavelength range ( 335-1000) nm, wildly used.

Built-in Single-Chip coumputer, high automaticity instrument, automaticly adjust 0%(τ), automaticly adjust 100%(τ) and zero tolerance τ-A switching, more handy than the original 721 model.

LED digital display

4 modes of measurement: transmittance(τ), absorbance(A), direct reading of concentration(C) and confficient determination(F), completely comply with testing requests.

Advanced optical system,superior C-T model monochromator’s  beamsplitter highly optimize these indexs :resolution, photometric accuracy, stray light.

Appropriative precision presetting lamp or a lamp holder. Our users don’t need to readjust light path when changing the lamp. It will be more handy for our users.

Sample room is made of special engineering plastic bearing solvent and strong sour alkali. In the bottom side installed a removable a container for liquid to meet needs of some of our users.

Staphylococcus tetragenus , 10-50 mm cuvette can be used

Insulated plastic shell, small volume, light in weight, good figure.
