Precision, innovation and reliability since 1992
inotech is the leading international manufacturer of calibration systems for meters, focusing on gas, water, heat and electricity meters. Bietigheim site in Germany, inotech Spain in Barcelona.

A focused company
inotech builds test and calibration systems for meters exclusively. This focus makes it possible to cover the entire flow and pressure range – from 16 l/h on a domestic gas meter up to 30,000 m³/h in the high-pressure closed-loop system.
Engineering, design, software development, manufacturing and acceptance are all in-house. The uniform user interface software links all system types, so operators can move between gas, water and heat test rigs.
Current development priorities are hydrogen test rigs, smart meter communication and optical detection methods.
