CALOMAT 62 is a thermal conductivity analyzer especially designed for applications in corrosive gases. The concentration of gas components such as Cl2, HCl and NH3 may be measured directly as well as gases such as H2 and N2 in aggressive atmospheres.  CALOMAT 6  is suited for applications such as chlorine-alkali-electrolysis, steel production and treatment, LNG processes, ammoniated synthesis, fertilizer production,  and petrochemicals.

The measuring principle of CALOMAT 62 is based on the measurement of thermal conductivity, a physical characteristic which is different for each gas. The signal is determined by a measuring bridge which consists of two electric resistances in the measuring gas channel and two resistances in the reference cell.  Depending on the application,  an isolated gas cell or a flowed reference could be used.

CALOMAT 62, similar to CALOMAT 6, allows for correction of cross-interference from residual gases. CALOMAT 62 is available in a compact 19 " housing as well as in a purgeable IP65 field case which provides gas-tight separation of the electronics and the Analyzer parts.
