The utility model discloses a parallel reaction ware electrode calibration device, include: the jar body, the take up is surveyed liquid, cover, lid close on the jar body to be provided with a plurality of sockets that connect, the electrode that awaits measuring is inserted and is established on connecing the socket, air inlet pipeline and exhaust pipe install on the jar body or cover, advance tobe provided with pressure measurement and gas control valve on exhaust pipe and/or jar body cover, the rabbling mechanism, the body acts on jar and in liquid make its misce bene, temperature electrode and/or standard thermometer insert to establish and are surveyed liquid temperature in order to measure connecing of cover in the socket, and thermoregulation mechanism, carry out heating and cooling to the jar body fluid body, mark anchoring mechanism, with it connects in order to carry out synchronous demarcation to the electrode that awaits measuring to observe and control system communication. The design connects the socket to establish the electrode that awaits measuring in order to insert on the cover, and the rabbling mechanism stirs the internal liquid that awaits measuring of jar and makes its inside materialization parameter even, has realized carrying on simultaneously a plurality of electrodes and demarcate under the same liquid environment of awaiting measuring.
