WTW inoLab® Multi 9310 IDS laboratory pH meter
This analytical measuring device is specially designed to meet the requirements of laboratories that demand maximum accuracy in the measurement of pH, conductivity and dissolved oxygen. Its robust construction, extensive functions and intuitive operation make it the preferred choice in many areas of chemical and biological research. Compared to similar models, it impresses with a universal measuring channel, flexible power supply and intelligent data storage, which leads to considerable time and cost savings in demanding working environments.
Detailed features and functions
The device is versatile and optimally tailored to the daily challenges in analytical laboratories. The most important features can be summarised as follows:
- Measurement channel: Universal (pH, conductivity, dissolved oxygen)
- Display: Large, backlit LCD graphic display for clear reading
- Data memory: Manual 500 or automatic up to 5000 data sets, ideal for reliable documentation
- Logger: Manual or time-controlled for complete recording of all relevant measured values
- Power supply: Operation with universal power supply (100-240 V, 50/60 Hz) or optionally via rechargeable battery (4 x 1.5 V AA or 4 x 1.2 V NiMH)
- Interface: Mini USB-B for easy data transfer to LIMS or PC
- Expandability: Optional thermal printer (58 mm wide) for direct printing of measurement data. In addition, there are additional performance features in the form of CMC/QSC functions, which enable reliable monitoring of measurement and calibration states. The integrated LCD graphic display is large and ensures that readings can be taken accurately and without fatigue, even over long periods of time or in changing lighting conditions. In addition, various parameter settings can be made in no time at all thanks to intuitive menu navigation, which makes everyday work noticeably easier.
The measuring device is suitable for use with various sensors: pH/ORP electrodes (SenTix® 9xx), conductivity sensors (TetraCon 925, LR925/01) and oxygen sensors (FDO® 925). This flexibility allows the instrument to cover a wide range of applications - from everyday checks in industrial laboratories to complex research projects in universities or specialised laboratory institutes.
Certifications and standards
Compliance with all relevant safety and quality requirements is essential for professional use in laboratories. This measuring system complies with current DIN and CE standards and meets the requirements for quality assurance in a wide range of industries. The instrument offers absolute reliability, particularly for applications in the pharmaceutical and food industries, where traceability and strict compliance play a major role.
Application examples

- Research and development in the pharmaceutical industry: Determination of the pH value in buffer solutions or fermentation media and measurement of dissolved oxygen in cell cultures.
- Environmental analysis: Recording the oxygen content in natural waters to monitor the ecological status of rivers, lakes and aquaculture.
- Chemical laboratories in universities: Teaching basic analytical methods and in-depth projects on pH measurement, conductivity measurement or oxygen analysis.
In all areas, users benefit from the ability to measure multiple parameters with a single instrument. Thanks to its ergonomic design, the device is also ideal for prolonged use.
FAQs
How is calibration performed?
The device supports automatic, multi-step calibration, which is controlled via the menu. Both pH and conductivity sensors can be calibrated with predefined buffer solutions or standards.
Which sensors can be used?
Compatible sensors include SenTix® 9xx for pH measurements, FDO® 925 for determining dissolved oxygen and TetraCon 925 or LR925/01 for conductivity.
Can it be used outdoors?
The system is basically designed for stationary laboratory environments. Occasional use outside the laboratory is possible, but transport and measurements outdoors should only be carried out under suitable conditions (e.g. protected from moisture).
What data interfaces are available?
A mini USB-B port is integrated as standard. This can be used to send measurement series directly to a PC. It is also possible to connect to a LIMS for convenient archiving and further processing of measurement results.
