Multiparameter
Meters and sensors for lab and field
WTW® is one of the major pioneers with more than 30 years of experience in the multiparameter measurement of electrochemical parameters such as pH, ORP, conductivity, ISE, and dissolved oxygen.Our high-precision measuring instruments combine state-of-the-art technology with intuitive handling for demanding analysis applications.
The new MultiLab® Pro IDS is an absolute highlight at the trade fair and sets new standards in intelligent multiparameter measurement technology. With its innovative IDS system (Intelligent Digital Sensor), the MultiLab® Pro IDS automatically detects connected electrodes and configures itself independently.
Specially developed electrodes guarantee reliable measurement results both under controlled laboratory conditions and in challenging field measurements. The innovative electrode technologies offer optimal response times and excellent reproducibility of the measured values.The spectrum ranges from measurements in surface waters to quality assurance in pharmaceutical companies.
Automatic documentation of all important sensor, device, and user data supports GLP (Good Laboratory Practice) in modern measurement operations. Benefit from our decades of experience in developing precise analytical instruments. We offer customized solutions for your specific measurement tasks in research, industry, and environmental analysis.

Electrodes and sensors
We have been developing and manufacturing glass electrodes for more than 80 years. Our electrodes have long been used for the most demanding tasks and are at home in laboratories around the world wherever they really matter. What began with a patent for pH electrodes now encompasses a range of several hundred different sensors: whether for ultrapure water, jam, wine, creams, or drinking water—we offer the right electrode for every conceivable application. Our extensive range of electrodes is as diverse as the applications themselves.
Highlights:
- Demanding laboratory measurement or mobile field measurement
- Robust plastic shaft or high-quality glass shaft
- Low maintenance or refillable
- Fiber/hole/platinum wire diaphragm
- Also available as IDS sensors
