Insert The Photometer Into The Sample

The 622 Photometer from Metrohm UK allows exact measurement of absorption and transmission as well as their direct conversion to concentration values.

The 622 Photometer allows exact measurement of absorption and transmission as well as their direct conversion to concentration values.

The analog output is used in combination with a titrator for the photometric endpoint determination.

A moderately priced, practical oriented alternative in photometry.

* Display of transmission, absorption and concentration : Transmission and absorption are the traditional measured quantities.Additionally, the 662 Photometer determines the concentration of sample solutions after previous calibration.

* Glass fibre 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.

* 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.

* Expensive cells are no longer needed: the long flexible glass-fibre light guide of the 662 Photometer makes photometric determinations just as easy as, for example, a pH measurement in a wide range of different vessels and over the entire visible wavelength range (400-700nm).
