Product description

Reliable online measurement of ORP – with DULCOTEST sensors

Our product line of DULCOTEST ORP electrodes provides a wide range of sensors for different measuring tasks. The fields of application cover everything from simpler water treatment tasks through to industrial process waters with more stringent requirements in terms of temperature, pressure, contamination tolerance and chemical resistance.

The production of our electrodes is subject to very strict quality controls. Routine steps are automated but critical steps are carried out manually under expert supervision. In this way we achieve optimum reproducible quality and cost reduction.

ORP potential is a measured variable that quantifies the presence of oxidants or reducing agents in a medium under specific conditions on a non-selective basis. Measuring this parameter is relatively inexpensive, but does have some drawbacks: no selective measurement of a specific oxidant / reducing agent, high dependence on pH, measuring signal tends towards a saturation curve as concentration increases. To measure specific reducing agents and oxidants selectively, without the above disadvantages, suitable amperometric sensors are used (e.g. chlorine sensors).

Your benefits

Precise and reliable measurement enables efficient processes and excellent process reliability
The wide choice of sensor types with different constructions makes them reliable components in many applications
A long service life is achieved through the use of select quality materials for the measuring electrodes and diaphragms and a stable reference system. This minimises both downtime and maintenance
With short storage times and fast delivery, your sensors can be up and running very quickly and you can make maximum use of their service life (all glass sensors start to age as soon as they leave production)
Wide range of special versions for fitting length, cable length and plugs for made-to-measure connection to your process

Field of application

The following list of applications are general examples of generally suitable applications for this product. Please contact your local sales representative to talk about the applicable use of this product in your specific case / environment.

Cyanide detoxification at a high pH value by means of oxidation
Chromate detoxification at a low pH value by means of reduction
Monitoring of disinfection effectiveness with oxidant metering
Swimming pool water, potable water
Process water
Chemically contaminated water
Cooling water, wastewater

Chlorine Disinfection

Various procedures are used to disinfect swimming pool water. Alongside the conventional metering of chlorine, use of cost-effective and environmentally-friendly electrolysis systems is also worthwhile for private pools.

Swimming Pool Water Treatment

Modern water treatment and disinfection processes enhance swimming enjoyment

The use of metering technology and water treatment solutions may vary considerably depending on the industry and application. Rely on our decades of experience and know-how to find the safest and most efficient solution for you.

(Pre-)Oxidation of Potable Water

(Pre-)oxidation binds harmful substances in potable water

(Pre-)oxidation improves water quality by eliminating many harmful substances and improving appearance, odour and taste. No one wants to drink brown water.

Disinfection of Potable Water

Germ-free potable water thanks to disinfection

As an essential nutrient, water must satisfy very strict quality controls. ProMinent offers sophisticated disinfection technology that reliably removes viruses, bacteria and microorganisms.

Cooling Water Treatment

Efficiency is everything in the cooling water circuit

Everything at ProMinent revolves around the perfect cooling water circuit, which needs to experience few losses over its long life. The precise metering of inhibitors and biocides and suitable filters make this possible.

Utility Water Treatment

It makes economic sense to reuse process water.

Why would you discharge water just because you've used it once? If this water is treated properly, it can be reused with ease, cutting costs in no time.

Waste Water Treatment

Very low-impact treatment for waste water

Our water treatment technology delivers thorough yet environmentally friendly waste water treatment. What's more, with precisely metered additives and optimised processes, you also save money.
