About CMTLAB
CMTLAB GmbH, based in Krefeld, is a young, independent company in the fields of IoT, Industry 4.0, process measurement technology and consumer electronics. The portfolio includes measuring platforms and transmitters for pH, redox, conductivity and temperature (96MU, FMU, MRP series), industrial-grade pH, redox, temperature and LF sensors, buffer and calibration solutions, and development tools such as signal simulators and interface converters. In addition, CMTLAB offers an engineering service: hardware and software development on behalf of customers, rapid prototyping, layout design, embedded software development (C, C++, C#, Android), lab automation, production test/test automation, and the transformation of prototypes into production-ready assemblies. The products can be networked via Ethernet, Bluetooth, USB, RS422 and 4–20 mA and are designed for IoT and Industry 4.0 applications. Customers are found in water treatment, drinking water, swimming pools, aquaristics, laboratories and the process industry.
