WTW inoLab® Multi 9620 IDS laboratory pH meter
The WTW inoLab® Multi 9620 IDS laboratory pH meter was developed for precise measurements in laboratories that place high demands on accuracy, repeatability and flexibility. It impresses with its advanced IDS (Intelligent Digital Sensors) technology, which guarantees interference-free real-time data and optimal adaptation to various applications. Those working in fields such as analytical chemistry, biotechnology, environmental sciences or pharmaceutical research benefit from reliable and versatile performance that surpasses many other devices on the market.
Versatile features and technical expertise
The measuring instrument covers a wide range of parameters: in addition to pH and mV measurement, oxygen parameters (such as concentration and partial pressure), conductivity (including resistance, salinity and TDS), temperature and turbidity are also available. In addition, the device enables simultaneous recording in two measurement channels. With a retrievable data volume of up to 10,000 automatically recorded data sets, extensive test series can be easily evaluated. The intuitive menu navigation via a colour LCD graphic display ensures quick navigation through the various measurement programmes. Continuous calibration with up to five calibration points for pH and up to seven for ISE (when using an adapter) also demonstrates the device's high practicality.
Important technical features at a glance:
- Measurable range: Depends on the IDS sensor used
- Internal storage: Manually up to 500 data sets, automatically up to 10,000
- Interfaces: Mini USB-B and USB-A for data export and networking
- Temperature compensation: For all parameters except redox
- Universal power supply: For flexible use regardless of the power source
- Multiple printer drivers: Enables direct printing without manual intermediate steps
- Suitable for analogue pH/redox/ISE sensors via ADA 94 pH/IDS
With CMC (Continuous Measurement Control) and QSC (Quality Sensor Control), the measured values and the status of connected sensors can also be continuously monitored. The integrated certifications - including CE and various ISO standards - prove that this device meets the most demanding quality and safety standards.
Specific areas of application
This multi-parameter system is suitable for a wide range of professional-level laboratory projects. Examples include:
- Environmental analysis: pH measurement and determination of the conductivity of water samples to gain insights into the condition of the water.
- Biotechnology: Testing oxygen concentrations in fermentation processes and simultaneous pH control to optimise microbial growth conditions. - Food industry: Quality control of beverages and foodstuffs through regular pH and conductivity measurements.
- Pharmaceutical sector: Monitoring pH values and conductivity in drug development and stability testing.
Turbidity measurement is particularly indispensable for investigations involving suspension solutions or emulsions. The device thus supports numerous work steps - from routine analyses to complex research projects.
