  • pH measurement with SenTix® electrodes

    pH measurement

    pH measurement is one of the most important and common measurements in the laboratory, the field and all water-based processes. The pH value describes the activity of the H+ ions, or how acidic or alkaline a solution is. The higher the activity, the lower the pH and the more acidic the solution and vice versa. The scale ranges from 0 to 14, with 7 being the so-called neutral point, which means that H+ and OH- show the same activity. The pH value is crucial for many biological, biochemical and chemical processes, its precise measurement is our concern!

    The right sensors for every application

    No two pH measurements are the same. The demands placed on pH measurement can therefore only be met by application-oriented and perfectly coordinated systems consisting of electrodes, measuring devices and buffer solutions, such as the ones we supply. A crucial component in this system is the pH electrode, which is in direct contact with the sample and delivers the measurement signal.

    We have been developing and manufacturing glass electrodes for over 80 years - know-how from which you as a customer benefit. Whether for ultrapure water, jam, wine, creams or drinking water – we offer the right electrode for every conceivable application.

    • Low-resistance membrane glasses guarantee stable measurement signals even at low temperatures
    • Silver ion-free reference electrolyte in conjunction with the unique platinum wire diaphragm in a large number of our laboratory electrodes prevents measuring problems caused by failing silver compounds
    • Functional slider for opening and safely closing the refill opening for electrodes with liquid electrolyte.

    IDS Sensoren

    IDS Sensors

    Modern devices communicate with a “smart” sensor in which the analog measured values are digitized in the sensor and are therefore transmitted to the measuring device in digital form. The digital measuring system is far less susceptible to interference during data transmission due to environmental influences (e.g. electrosmog or cable length). Xylem Analytics has designed the IDS sensors that not only signal conversion takes place in the sensor, but also calibration data, calibration protocols and serial numbers are stored in the sensor head to clearly identify a sensor. There is a large selection of IDS sensors available for all parameters


    • Reliable measured values through signal processing in the sensor
    • Easy electrode replacement thanks to calibration data stored in the sensor
    • Sensor quality monitoring through QSC function

  • Titration

    Titration is one of the oldest methods for content determination in chemistry. In contrast to gravimetry, no sparingly soluble compounds are dried and weighed, but a reagent of known concentration is added to the dissolved sample until the chemical conversion is complete. Titration finds broad use in chemical analysis. On the one hand, a titration can be performed very easily and quickly. On the other hand, titration provides a very accurate measurement result after only a few minutes - under optimal conditions.

    SI Analytics® titration devices have been known for more than 45 years for their high accuracy, robustness and flexibility.

    The product portfolio ranges from the simple TITRONIC® 300 piston burette for simple dosing tasks and manual titration to the TitroLine® 7800 / TitroLine® 7800 -TitriSoft with sample changer TW 7200 for complex titration tasks and TitroLine® 7500 KF trace with headspace oven/sampler TO 7280/TW 7650 for fully automatic water determination according to Karl Fischer.

  • Photometry and Turbidity

    Photometers are universal measuring tools that are used for everything from research and teaching to environmental and process monitoring. In the environmental sector, for example, they are used to monitor surface and groundwater. In quality control, they are used in the food and beverage industry as well as in drinking water production. The proven and highly precise WTW® photometers can be used for a wide range of these applications. The reason for this is the large selection of commercial test kits, as well as reagent-free methods and the possibility of colour measurement.

    The devices in the photoLab® series are also capable of performing the tasks required in research and service laboratories, such as scans, kinetic and multi-wavelength measurements or complex multi-step analyses.

    The photoLab® 7600 UV-VIS spectrophotometer adds reagent-free COD, nitrate and nitrite measurement via OptRF to the comprehensive range of proven routine measurements.  It can also determine important parameters such as UVT and SAC and carry out extensive colour measurements. As lightweight devices, the photoLab® series can also be used on the move with a car battery.

    The robust and intuitive photometers in the photoFlex® series are particularly impressive in the field. From the simple photometer to the "Swiss army knife", which combines 4 devices in one multi-parameter device, these are ideal for all applications that require mobility and versatility.     

    Turbidity is a subjective, optical impression and therefore not as clearly determinable as the photometric parameters, for example, but rather an effect caused by the scattering and absorption of light. Nevertheless, turbidity has proven to be an important parameter for quality assessment and control. Turbidity measurement has long been used worldwide in drinking water to determine quality for human consumption. A standardised measurement method for reliable quantification has been developed for this purpose: The measurement method used today in drinking water with a scattered light measurement of 90° is known as nephelometric turbidity measurement and is described in the two standards DIN EN ISO 7027-1 and US EPA 180.1. However, methods of turbidity measurement have also been established in the medical/pharmaceutical sector and in food production, e.g. to monitor production processes or shelf life. In wastewater treatment, turbidity measurement is used as an indicator for mass loading.

    Xylem Analytics offers proven, high-precision WTW turbidimeters for the various applications of turbidity measurement. From quality monitoring in the laboratory to environmental monitoring in the field.

    The WTW Turb® 750 IR and Turb® 750 T fulfil the requirements of many laboratory and industrial applications for AQA-supported turbidity measurement. With the help of the Intelligent Reproducibility and Plausibility Check (IRPC), they deliver highly precise measurement results.
