Metrohm 905 Titrando

Titrator image The Metrohm 905 Titrando is a multifaceted instrument that allows automated dual and/or parallel titrations of samples. Its total automation increases sample throughput and greatly improves accuracy. The software is flexible, and can accommodate numerous titration schemes. The S-LAB has optimized the Metrohm Titrando for parallel total alkalinity analysis by Gran titrations and total dissolved oxygen analysis by the traditional Winkler method. The S-LAB titrando system includes the Metrohm 856 Conductivity Module, which can be used to rapidly and accurately determine salinity.
