Compur 4120 Switch position for H2S, Switch position for HCN, Switch position for COCl2

Compur Statox 4120

DIP switch S1 (see pic. 8) programs gas and measuring range. If you change your Statox to another gas or measuring range, a hardware modification may be required and the electronics must be re - adjusted. This must be done by authorised personnel.
