Accredited calibration laboratory for gas flow, pressure, temperature and humidity
The inotech calibration laboratory in Bietigheim is accredited by DAkkS to DIN EN ISO/IEC 17025:2018 (D-K-23505-01). We calibrate in the laboratory and at your site – with the same measurement uncertainty.
Calibration and measurement capabilities (CMC)
Extract from the annexes to the accreditation certificate, valid from 12 Aug 2026. All quantities are also accredited for on-site calibration – with identical measurement uncertainty.
Critical flow nozzles and gas meters, in-house methods AA-108.005 to AA-108.007, calibration with atmospheric air. In the laboratory, above 2,650 m³/h only for systems with their own flow generation.
DKD-R 6-1:2014, pressure medium gas.
DKD-R 5-1:2023, comparison with reference thermometer in a liquid bath.
DKD-R 5-8:2019, electrical hygrometers with display in a temperature/humidity generator, medium air at 20 °C to 30 °C. Uncertainty as an absolute value of relative humidity.
Measurement, f = respective measured value.

What we calibrate
Nozzles, reference and transfer meters from gas meter test systems – regardless of the system manufacturer.
Pressure gauges, resistance thermometers and hygrometers from test systems and production.
Test equipment from meter production and comparison meters for ongoing quality assurance.
A specific measurement uncertainty budget for every test system – regardless of the manufacturer and the installed components.
In the laboratory or at your site
Flow calibration with atmospheric air up to 6,500 m³/h, plus pressure, temperature, humidity and frequency.
The system stays where it is and production keeps running – a unique advantage over suppliers that calibrate only in their own laboratory.
How calibration works
Quantity, measuring range, number of items and preferred location – in the laboratory or on site.
We agree on calibration points and a date and, if required, plan the visit to your system.
According to DKD guidelines and accredited in-house methods, traceable to national standards.
DAkkS calibration certificate with results and expanded measurement uncertainty.
