These very compact, easy to operate instruments are ideal for coulometric water determination according to Karl Fischer in low water content, as well as for bromine number determination. They are suitable for small liquid or gaseous sample amounts, and can be used for quality control in the chemical, petrochemical, pharmaceutical and food industries.
