Page 69: Operation And Maintenance
Maintenance of the pH Meter/Conductometer is best carried out as part of annual service, which is performed by specialist personnel from Metrohm. A shorter maintenance interval may be necessary if you fre- quently work with caustic and corrosive chemicals. Metrohm Service offers every form of technical advice for maintenance and service of all Metrohm instruments. -
Page 70: Quality Management And Qualification With Metrohm
Maintenance The electronic and mechanical modules of Metrohm instruments can and should be checked by specialist personnel from Metrohm as part of a reg- ular preventive maintenance schedule. Please ask your local Metrohm rep- resentative regarding the precise terms and conditions involved in con- cluding a corresponding maintenance agreement. -
