Acoustic Thermometry

Completed
By measuring the speed of sound in argon gas, we have determined thermodynamic temperature with unprecedented accuracy in the range 0 °C to 552 °C. Our results

Cold Core Technology Platform

Ongoing
We are building a cold-atom based sensor program that represents a new approach to metrology—to establish a set of chip-scale tools that enable real-world use

Dynamic Pressure

Ongoing
Manufacturing processes by their very nature require a judicious, time-dependent use of pressure and temperature to transform a base material into a valuable

Fixed Point Development : Non-Metals

Ongoing
We are developing new fixed points and new maintenance systems for use with Standard Platinum Resistance Thermometers (SPRTs) below the triple point of water

Humidity

Ongoing
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)

Humidity Calibration Services at NIST

Ongoing
Humidity calibrations at NIST are performed using its state-of-the art primary standard humidity generator. Calibrations are performed on instruments that

Johnson Noise Thermometry

Completed
Johnson noise thermometry (JNT) is a primary temperature measurement technique based on the fundamental properties of thermal fluctuations in conductors. We

Photonic Dosimetry

Ongoing
As part of the NIST on a Chip program, the Photonic Dosimetry project is developing in-situ sub-micrometer ionizing-radiation dosimetry and calorimetry leading

Photonic Thermometry

Ongoing
Photonic Thermometry is a cutting-edge research program at NIST that aims to break the fundamental limitations of electrical resistance-based thermometry and

Pressure

Ongoing
The NIST Thermodynamic Metrology Group (TMG) provides critical research into pressure measurement capabilities improving uncertainties in user facilities and

Reliable Vaccine Storage

Ongoing
We study provider-level vaccine storage and temperature monitoring methods to develop best practice guidance for public health audiences.

Thermometry

Ongoing
The NIST Thermodynamic Metrology Group maintains and develops national standards of temperature (in the range 0.65 K to 2011 K), and supports calibration of all
