Metrohm AG products

This family of pH and conductivity meters are your ideal companion for routine use. You can use the instrument as a portable meter or as a benchtop instrument in the laboratory. Thanks to a large color display, a rugged design, and smart technology, these meters will make pH value and conductivity measurement as easy as never before.

The 780 pH Meter and 781 pH/Ion Meter are the instruments of choice for those seeking an elevated level of technical comfort and freedom in their measurements of pH, ORP, Ipol, Upol, and ion concentrations. The meters, which are equipped with built-in quality assurance, guarantee reliable results at all times. Features such as the internal method memory and the possibility to connect different accessories account for that extra bit of convenience.

With the 856 Conductivity Module and 867 pH Module, you can build your own, customized solution – whether you are analyzing large sample loads or multiple parameters, or you want to enjoy full freedom when it comes to method programming and applications. The modules combine the highest level of flexibility and technical comfort with modern measuring technology and are fully FDA-compliant.

Portable two-channel pH / conductivity measuring instrument with intelligent measuring input for measuring pH/mV / conductivity / TDS / salinity and temperature. You will be optimally equipped for measurements in the field with this battery-operated measuring instrument.

Portable two-channel pH / conductivity measuring instrument with intelligent measuring input for measuring pH/mV / conductivity / TDS / salinity and temperature. You will be optimally equipped for measurements in the field and in the laboratory with this battery-operated measuring instrument with stand plate.

Conductivity measuring module as supplement to an existing Titrando system or "stand-alone" in combination with a 900 Touch Control. With the 856 Conductivity Module, not only conductivity and temperature can be determined, but also TDS and salinity. It supports state-of-the-art conductivity measuring cells, i.e. 5-ring measuring cells. Thanks to the galvanically isolated measuring input, pH value and conductivity can be measured in the same beaker without interference. The Conductivity Module is equipped with two USB interfaces for connecting printers, barcode readers or sample changers and four MSB interfaces for stirrers or Dosinos. Both in conjunction with the 900 Touch Control as stand-alone instrument and also integrated in tiamo™ full (from 2.0), it is in compliance with GLP and FDA 21 CFR part 11 requirements.
