Mettler

Process acidity or alkalinity, temperature and pressure, the presence of organics, etc., all affect a pH sensor's ability to measure reliably. For this reason METTLER TOLEDO has a wide range of pH sensors available so that you can choose the correct one for your process. Simply complete the form below and the pH Sensor Selector will show you the sensor that meets your exact needs.

Enter your process data then press Search

Process pH

Maximum process temperature

0°C/32°F

130°C/266°F

Maximum process pressure

0barg/0psig

15barg/218psig

Does your process contain any of the following? (select all that apply)

If you select pH is lower than 6 and your process contains Fibers (or process medium is a slurry), you must select Hydrofluoric acid in your process data

Oxidants (e.g. chlorine, peroxides)

Hydrofluoric acid

Fibers (or process medium is a slurry)

Suspended particles

Sticky hydrocarbons (e.g. crude oil, ethylene quench water)

Polar organic solvents (e.g. acetone, ethanol, formaldehyde)

Nonpolar organic solvents (e.g. toluene, benzene, naphtha)

To increase measurement performance and sensor lifetime you may want to consider automated sensor cleaning and calibration.

Are you measuring in pure water (e.g. boiler feedwater, demi water, condensate)?

What type of sensor do you require? What is ISM?

None
Standard (analog)
ISM (digital)

The innovative METTLER TOLEDO «Intelligent Sensor Management®», concept makes
it decidedly easier to operate process analytical systems from initial installation to
maintenance right through to sensor exchange. ISM technology enables you to lower
maintenance costs and reduces the risk of sensor failure.
