What is a gas density monitor?
Gas density monitors
The gas density monitor is based on the principle of reference gas comparison and therefore no temperature compensation is necessary. It works electromechanically and is thus independent of electrical energy supply. Since no recalibration of switchpoints is needed, it operates maintenance-free.
