GRANT-KSH acid and alkali aerosol analysers

Signalisers are automatic stationary devices of general industrial purpose, working on the principle of cyclic flow-injection chemical analysis. The analysers consist of a measuring unit, a control unit, a matching unit, a pneumatic unit and a control device located in a cabinet. The measuring unit has openings for distilled water supply and drainage of the analysed sample and is connected to the pneumatic unit by a tube for air pumping. On the matching unit there are relay contact outputs with the possibility to connect external sound alarm and analogue current output 4-20 mA. On the door of the cabinet there is a light signalling system.
