Product comparison

Compare by the engineering decision—not only the model number.

This shortlist connects each measurement task to the relevant product family, selection guide and quotation path. Published facts come from the supplied technical files; the final configuration is confirmed against the water matrix and installation.

Selection matrix

Seven common buying decisions.

Use the family page for specifications, then the guide for application criteria. Send the resulting shortlist with your normal and peak conditions for a formal recommendation.

Measurement taskShortlistDecision boundaryNext step
01Industrial pH

Which electrode construction fits the water matrix?

13 XF application-specific pH sensors

XF232 · XF240 · XF260E · XF263 family · XF264 · XF266 · XF268 · XF288

Compare temperature, pressure, junction, body material, installation and contamination risk.

02Dissolved oxygen

Full-size, compact or aquaculture configuration?

PFDO-500 / 600 / 700 / 800

0–20 mg/L fluorescence measurement across the documented series

Compare probe dimensions, pressure rating, construction and the actual installation environment.

03Turbidity

Low-range drinking water or wider process range?

PLTU-600 / 700 · PTU-500 / 600 / 800

Low-range flow-cell and immersion configurations

Select by the normal and peak NTU range, optical method, sample flow and cleaning requirement.

04Suspended solids / MLSS

Suspended-solids trend or high sludge concentration?

PSS-600 / PSS-800

Wastewater, activated sludge and industrial process water

Compare concentration range, process stage, fouling load, automatic cleaning and mounting.

05Residual / total chlorine

Colorimetric or electrochemical measurement?

CL-201 · PDCL-400 / 500M / 600 / 700

Free chlorine, total chlorine, active chlorine and chlorine dioxide options

Confirm analyte, range, sample pH, conductivity, flow, maintenance method and reagent preference.

06Portable measurement

One parameter in the field or a laboratory test program?

PMI800 · VX · VN · VI

Eight PMI800 sensor configurations plus laboratory and field analyzer families

Choose by parameter, measurement principle, field protection, data handling and required test programs.

07Integrated systems

Controller, compact cabinet, sampler, buoy or automatic station?

MUC-200 · PWQ-1000 · PAS-305A · PB buoys · PMA9000

From a seven-sensor controller to a complete automatic monitoring station

Start from parameters, site power, sample conditioning, communications, enclosure and maintenance access.

Before quotation

Six details prevent a wrong selection.

A model match based on one headline range is not enough for an online measurement project.
