Precise measured values form the basis of every controlled process. Bürkert offers measuring devices for liquid analysis in a wide range of applications – from drinking water treatment and pharmaceutical pure water systems to industrial process monitoring in the food and energy industries. From individual sensors to system solutions, we supply the right measurement technology for your process needs.
Cube technology
Compact analysis in the smallest of spaces
Bürkert’s modular sensor cubes combine multiple measuring parameters in the smallest of spaces – for a low-maintenance solution that is networked via a common interface. If required, you can obtain a finished system in a ready-to-use control cabinet: simply connect the water line, switch on the power and start analysing.
What sensors does Bürkert offer for liquid analysis?
Bürkert offers a wide range of measurement technologies for water-based media. Measuring parameters, the measuring range and the specific requirements of your system, based on your industry and application, are essential factors in making the right choice.
Measuring parameters: pH value, ORP, conductivity, chlorine and more
Bürkert’s range includes all measured quantities that are relevant to liquid analysis:
Conductivity: from concentrated solutions to ultrapure liquids in CIP processes, for example
Chlorine: free chlorine and total chlorine in drinking water, seawater and process water; reliable measurements even at low concentrations
Turbidity: detection of unwanted, undissolved substances in drinking water, e.g. for monitoring filter effect
Iron: fully automatic determination by means of flow injection analysis; for example, when monitoring water treatment processes
SAK254: detection of dissolved organic substances in water, e.g. for quality assurance in drinking water production
Nitrate: reagent-free and low-maintenance UV measurement; for example, to ensure compliance with legal limit values in drinking water applications
It is also possible to record multiple parameters in a single system – including pH, conductivity and turbidity, combined in one drinking water facility.
Which sensor technologies are available?
Bürkert gives you the choice between two sensor technologies for liquid analysis:
Insertion sensors are a proven solution used widely in pipelines and process containers. They cover the entire spectrum of applications, from ultrapure liquids to contaminated process media and aggressive cleaning liquids.
Bürkert cube technology is a compact alternative for drinking water and pure water applications. The modular sensor cubes can be flexibly combined, require very little maintenance and communicate via a common interface. Both technologies can be used flexibly, from single sensors to complete system solutions. Bürkert also offers microsensors for highly specialist applications in fields such as laboratory analysis.

What makes Bürkert sensors for liquid analysis so special?
Uniquely compact technology
Cube technology is only available from Bürkert: a uniquely compact system for liquid analysis that’s ready for immediate operation and is low-maintenance.
Adapted to your requirements
We configure the right measurement technology for your individual processes, whether you’re focused on measuring parameters, measuring ranges, measuring accuracy, hygiene requirements or certifications.
System solutions from measurement to control
Bürkert doesn’t just supply sensors. We are also your point of contact for all things control circuits: measurement, control and regulation from a single source, with everything working in perfect harmony.
Areas where our sensors are used
In pharmaceuticals and biotechnology, for example, Bürkert sensors monitor pure water, steam sterilisation processes, autoclaves and fermenters. They use hygienic process connections and certifications for FDA or EHEDG as standard.
In the energy sector, for example, they can be found in electrolysers and hydrogen production, and ensure process stability.
In the food and beverage industry, Bürkert sensors monitor substances such as process water and cleaning liquids – in any application where hygienic design and CIP processes are required.
In general process water monitoring, Bürkert sensors provide reliable measured values wherever water quality is an important process parameter.
Cube technology is a particularly popular option for drinking water treatment. It delivers a strong performance in even the tightest of spaces – for example, in mobile treatment containers that are able to produce safe drinking water within just a few hours.
In the field: robust sensors for production processes in solar, semiconductor and medical technology
RENA relies on Bürkert conductivity sensors for wet chemical surface treatment. They reliably monitor factors such as acid and alkali concentrations or ultrapure water quality even under aggressive process conditions.
Our portfolio covers numerous common measuring parameters and application scenarios – for pharmaceuticals, biotechnology, food, energy and many other industries.

To recommend exactly the right sensor for you, it is important to know the following information:
The required measuring parameter
The relevant measuring range
The required measuring accuracy
The temperature, pressure and chemical composition of the medium
Other factors that are important to the sector in question, such as hygiene and certification requirements in the pharmaceutical and food industries
The chemical resistance depends on the medium being used: aggressive acids, alkalis and saline liquids place specific demands on the housing material and electrode. Bürkert supplies sensors in various types of materials, including PP, PVDF and PEEK. We will be happy to advise you if you are unsure about media compatibility.
Bürkert offers sensors with FDA conformity and EHEDG certification for pharmaceutical and food applications. Other certifications are also available depending on the product and application.
Yes. In drinking water treatment in particular, multiple parameters are usually measured in parallel – these may include pH value, conductivity and turbidity. Several Bürkert sensors can be combined to form a system solution that is connected via a common interface.
