New compact online pH analyzer – a great alternative to inline pH measurement

Online process analyzer for pH determination in industrial processes and wastewater streams

Metrohm Process Analytics now offers the 2026 pH Analyzer, part of a new family of economical online process analyzers. These powerful, compact process analyzers are integrated solutions for 24/7 online analysis of critical chemical parameters in industrial processes and wastewater streams. These single-method systems are available in several application-specific configurations for monitoring up to 2 process streams.

Compact analyzer for online pH measurements

The 2026 pH Analyzer performs pH measurements online for up to 2 sample streams, saving valuable time for process operators. Potential hazards and safety concerns regarding critical pipeline sample points are removed as the pH electrode does not need to be retracted for tasks like cleaning. The electrode condition is continuously monitored, and calibration and cleaning is done automatically. A 7” full-color touchscreen shows trend graphs and allows easy access to your data. These process analyzers are a great fit for process analysis especially in the chemical, food and beverage, potable water, and industrial wastewater sectors.  

Customized for your application

The analyzer is especially suitable for applications which would otherwise require manual operator intervention, or processes in which glass electrodes are too hazardous to use. Metrohm Process Analytics can offer process analyzers which are configured for each specific application challenge. Sample dilution, extra reagents, or even another sample stream can be added with the addition of peristaltic pumps in the modular wet part.

Robust design (IP66)

Strict separation of wet part and electronics ensures safe operation in harsh environments. The electronics part is housed within non-corrosive polyester-coated stainless steel. With an Ingress Protection rating 66, the 2026 pH Analyzer is guaranteed to be dust and water-tight.

Virtually unlimited sample conditioning options

Metrohm Process Analytics provides virtually any sample preconditioning system, such as cooling or heating, pressure reduction, degassing, filtration, and more.

Diverse data communication

Information including results, remote control and status info, can be communicated through discrete I/O (i.e. analog outputs digital in/outputs), MODbus TCP/IP (Ethernet), or RTU (RS485) communication. Remote control is possible through VNC (Ethernet). Results can also be exported to USB.
