FAQs

What are the pH accessories used for?

The addition of pH accessories to the electrochemistry system enhances and customizes the measurement process. METTLER TOLEDO offers printers, electrode arms, modular expansion units, and stirrers as pH accessories. pH accessories are available for both benchtop and portable pH meters for use in the lab or the field.

 

Which pH accessories help increase data security?

Accessories for enhanced data security include printers, barcode readers, and data export capabilities. Printers provide an easy way to document measurement results on paper. Barcode readers reduce potential errors during transcription, and various meters support PDF format export onto a USB memory stick.

 

What are the benefits of an electrode arm?

Correct sensor positioning is key to a correct sample reading. Holding the sensor by hand can be an option, however, an electrode arm offers several benefits. Precise positioning and a perfect vertical move make handling easier and prevent sensor damage or sample vessel tipping. If you plan to use multiple sensors, the electrode arm should be able to hold them either in measuring or storage positions.

 

Why is using a magnetic stirrer important?

Stirring is essential for reproducible results in measurements of pH, conductivity, and ion concentration. Investing in a magnetic stirrer generates several key advantages: programming of the desired stirring behavior as part of the measurement method, or the option to add pre-stirring and wait periods. Calibration and measurement must be done under the same conditions.

 

Which printers can be used with the SevenExcellence™ meter?

Three types of printers can be used with SevenExcellence™:

  • Network printers: the content of the printout is the same that you get when creating a PDF file on a USB memory stick. It is not possible to connect a standard PC printer to SevenExcellence directly, only via Ethernet connection.
  • USB compact printer, e.g. the USB-P25 printer: the same information as on a PDF file is printed, but in a more compact format.
  • RS compact printers, e.g. RS-P25 or RS-P26: same print-out content as with USB compact printer, but via RS232.
