M300 & M300 ISM TransmitterReliable, Versatile, Easy to Use

The METTLER TOLEDO Thornton M300 transmitter line for conductivity / resistivity, pH/ORP, dissolved oxygen, ozone and flow rate combines robustness with ease of use. Its versatility and solid measurement performance makes it the ideal choice for light industrial applications. The M300 transmitters are designed for comforta-ble operation: from the large display to the easily accessible wiring terminals to the plain text interface and quick setup menu. With its innovative USB port, the M300 is open to the future – for remote configuration and commissioning. M300 ISM ver-sions provide the beneficial Plug and Measure feature thanks to ISM functionality.
