Gaithersburg MD, USA — The NIST Selecting and Using Alternative Thermometers Mini-Workshop is offered every year and is a laboratory-based workshop designed to assist those in industry in the conversion from mercury thermometers to safer alternatives.

NOTE: This article is published for information only; registrations for the course are limited and must be made in August. If you are interested, it is not too soon to contact NIST about the next course.

The workshop covers different types of alternative thermometers, selecting the best alternative thermometer for your measurement application and uncertainty, calibrating alternative thermometers, and ???in-the-field??? validation methods.

Lecture Topics:

Overview of alternative thermometers

I. Application-based selection
II. Measurement equipment
III. Measurement differences between analog and digital thermometers
IV. ITS-90 vs E1137 equations

Using a digital thermometer ??? Hands-on in the laboratory

  • Measurement differences between analog and digital thermometers
  • Use and care of a digital thermometer
  • Validation techniques
    • Ice melting point
    • Steam point
  • Field-use of a digital thermometer
  • Calibrating a digital thermometer by comparison
      o ???196 ??C to 500 ??C


The registration fees for the 2012 Selecting and Using Alternative Thermometers Mini-Workshop is $1,200 per participant per workshop for the complete 2-day course. The registration fee must be prepaid in order to guarantee your participation in the workshop.

Pre-registration is required. Registration for the course is limited to 4 attendees on a first-come, first-served basis.

Registrations will be accepted in the order they are received by NIST. Registration and payment must be received by Monday, August 17, 2012. There will be no on-site registration. Cancellations and/or substitutions must be requested, in writing, by Monday, August 17, 2012, and no refunds will be made after this date unless a replacement is found.

The Short Courses offered by the Sensor Science Division of NIST’s Physical Measurements Laboratory (PML)

ITS-90 Fixed-Point Cell Mini-Workshop, September 17-18, 2012

The workshop covers the realization of ITS-90 fixed-point cells over the range from the mercury triple point to the zinc freezing point for the calibration of SPRTs and the development of uncertainty statements for the fixed-point cells and subsequently SPRT calibrations.

The Division also offers short courses in radiation thermometry, photometry, spectroradiometry, and spectrophotometry on a biennial basis.

In addition, the Division offers workshops on fixed-point cells and alternative thermometers. Attendees include NIST staff and representatives from industry, national laboratories, and other national metrology institutes.

The courses consist of lectures and skill-building, problem-solving laboratory experiments. The content of the courses typically includes the following topics: practical laboratory experiences, proper uncertainty analysis, and treatment of the measurement equation.
