METTLER TOLEDO SevenCompact Benchtop Meter

From $1,102.95

Mettler Toledo SevenCompact meters are the perfect choice for a wide range of applications without overstretching your budget. Choose the pH/Ion S220 to measure pH, ORP, and ion concentration in various units. The Conductivity S230 measures conductivity, salinity, resistivity, total dissolved solids, and conductivity ash.

The included electrode holder with perfectly vertical uPlace movement helps you bring your electrode in the position where it works best for your sample. This allows for faster measurements and reduces the risk of the sample vessel tipping over and/or damaging the sensor.

View all measurement information on the display, or just focus on the essentials with the uFocus view. Only a single keypress switches between the different display layouts.

Choose from the meter alone or the kit which includes:

S220-Kit: InLab Expert Pro-ISM, Guide to pH measurements and 2 buffer achets for pH 4.01, 7.00, 9.21, and 10.00
S230-Kit: InLab 731-ISM, Guide to conductivity and dissolved oxygen, 2 calibration sachets for 1413 μS/cm and 12.88 mS/cm

Key Features

  • Budget-friendly
  • Universal and versatile
  • uPlace electrode holder for ease-of-use
  • Easily switch between different display layouts
