Humidity calibrations at NIST are performed using its state-of-the art primary standard humidity generator. Calibrations are performed on instruments that
The lack of repeatable process outcomes from additive manufacturing (AM) has been broadly acknowledged as an impediment to widespread implementation. While most
The NIST Thermodynamic Metrology Group maintains and develops national standards of humidity (in the range 1 nmol/mol to 0.6 mol/mol of water concentration)
The lack of repeatable process outcomes from additive manufacturing (AM) has been broadly acknowledged as an impediment to widespread implementation. While most

The 10th International Temperature Symposium (ITS10) was held in Anaheim California on April 3rd to 7th, 2023. More than 180 abstracts were received and
We describe the model and construction of a two-flow (or divided-flow) humidity generator, developed at LNE-CNAM, that uses mass flow controllers to mix a

We describe here the calibration of customer hygrometers using the NIST Hybrid Humidity Generator (HHG). This generator produces humidified air with water
A Consultative Committee on Thermometry (CCT) Key Comparison of frost point temperatures was carried out by the National Institute of Standards and Technology
This project has been completed. The paper reporting the results is provided here . The NIST Thermodynamic Metrology Group (TMG) used its standard gravimetric
The NIST Hybrid Humidity Generator (HHG) is NIST’s primary standard humidity generator and is used for calibration of all hygrometers sent to NIST. The HHG and
