This six minute video by the National Institute of Standards and Technology (NIST) describes the types of mercury-containing thermometer alternatives that are currently available for use today in laboratory and industrial applications. This video and the similar ones on the EPA website (www.epa.gov/mercury/nistvideo/index.html) are important adjuncts to the recently announced Calibration Policy change at NIST, [...]
This six-minute video by AquaLab captures the correct way to check, verify and if necessary, adjust some ordinary thermometers using an ice bath. Most people think that it’s easier to do so at the boiling point of water, but the ice point (very nearly 0.01 ° C at all normal atmospheric pressures) is far more [...]
About a unique Triple Point Cell based on Ethylene Carbonate developed at Britain’s National Physical Laboratory (NPL) in a nearly 4 minute video from YouTube. It’s kind of a commercial, but a really useful one. It explains about this special calibration tool and how it can and is being used to help verify the calibration [...]
From Fluke Corporation In this video Matt Newman from Fluke Corporation’s Hart Scientific Division (www.HartScientific.com) demonstrates the proper technique for realizing a triple point of water cell for temperature calibration. Triple point of water cells are used for calibrating a variety of precision thermometers. The triple point of water cell is an intrinsic standard with [...]
