Currently certification coordinator in the certification schemes Inspection Specialist (SKK) and Non-Destructive Testing (SKNDO).Previous I was a metrologist with a long term experience in temperature and humidity at the highest level. To fulfil needs of customers, I developed new setups providing traceability to (inter)national standards, such as:- High temperature relative humidity chamber up to 180 °C and pressures up to 600 kPa able to generate dew-point temperatures up to 150 °C.- Primairy dew-point temperature generators in the range from -80 °C up to 95 °C and pressures up to 6 MPa.- Water bath for calibration of thermometers with uncertainties as low as 0.7 mK in the range from 0 °C up to 70 °C.- Low temperature cryostat calibration of thermometers with uncertainties as low as 4 mK in the range from -195 °C up to -80 °CFor more information see Research experience and (full) Publication list both included under featured.
