  • Radiation Thermometer IT-460 with the Fastest Thermopile

    One of the tools to measure the surface temperature of an object without contact is the radiation thermometer that measures the dose of infrared rays emitted from the surface of the object. HORIBA's radiation thermometer, available in various types to meet a wide range of applications, were demanded to improve their response time in applications to measurement of moving objects or observation of ...

  • What specification thermometers are available, and what are the differences?

    Thermometers are used in most laboratories across all industries, and a wide range are available to suit any temperature monitoring task. For high accuracy applications that need to adhere to international standards, traditional glass specification thermometers are still the most popular choice. Specification thermometers are those which are manufactured to conform to internationally recognized ...

  • Influence of seawater Sr content on coral Sr/Ca and Sr thermometry

    The Ca content of a Porites coral from Xisha, South China Sea is quite uniform along its 18-year growth axis. A comparison with previously published data shows that the Ca content of corals from different sites varies by only 0.4%. This is much smaller than the variation of Ca in seawater (2.2%), indicating that Ca variations in seawater do not significantly affect the Ca compositions of coral ...

  • Basic tests for checking validity of field data

    The following guidelines are suggested for verifying micrometeorological data gathered in field experiments. It is assumed, for simplicity, that the observations being tested are made over open, relatively flat and uniform terrain, with small roughness elements. It is also assumed that the sensors and the data acquisition and recording hardware are basically sound and that the purpose of the ...

  • Mercury free solutions for autoclave temperature monitoring

    Mercury is a naturally occurring element found in the air, water and soil however exposure to the substance, even in small amounts, can lead to severe health and ecosystem issues. Mercury in products can find it’s way into the environment in all sorts of ways such as manufacturing, spills, recycling and disposal. Due to the health risks posed products such ...

  • Some thoughts on in-situ flux measurement in the atmospheric surface layer

    Due to its complexity, the state of a turbulent atmosphere can only be described using statistical quantities such as means, variances, and covariances. Computation of these statistical quantities, particularly those of higher order, must be done with considerable care. This is particularly true if the statistics are used to depict heat and momentum fluxes. This note contains considerations that ...

  • Another look at sonic thermometry

    Abstract. In this note we reassess the role of sonic thermometry in boundary-layer studies. The sonic temperature signal, when corrected for crosswind velocity contamination, very closely approximates the virtual temperature of air. This variable is needed for many boundary-layer calculations. We describe preliminary tests with a new sonic anemometer-thermometer that performs the velocity ...

  • Sonic temperature significance and limitations

    The ATI sonic thermometer measures temperature from transit times t1 and t2 measured along the vertical path of the anemometer's probe. They are the times taken by sound pulses to traverse the 15-cm acoustic path in opposite directions; (these same transit times are used also for computing the vertical wind component). The instrument exploits the strong dependence that exists between the speed ...

  • Determination of Ultra-Trace Mercury Vapor Levels from Industrial & Military Metal Components

    For many years, scrap metal reclaimers did not separate the materials containing mercury from other metals. Such things as mercury switches, dental amalgam, thermometers, and refining wastes from copper, gold and silver were processed along with the typical industrial metals. The result is that a significant portion of the Ferrous and non-Ferrous metals and alloys used today contain some metallic ...

    A smarter way to take a temperature A Northern California lab automates data- gathering and hands the tracking responsibility over to a computer François Rodigari and Kenneth E. Osborn One of many things that environmental laboratories must do is to track and document the temperatures of the laboratory's incubators and refrigerators. This means that the thermometers used to ...

  • Help protect children from environmental risks

    October is Children’s Health Month. To heighten awareness about environmental issues impacting children, EPA is providing parents and caregivers simple tips they can use to help protect children in their homes, schools and communities.“As both EPA Administrator and a mother, I understand the importance of protecting our children from environmental threats,” said EPA Administrator Lisa P. Jackson. ...

  • Heavy Metal(s) in Every Day Electronics

    “Heavy metal” isn’t associated only with rock music. In sustainability, it refers to real metals like cadmium, mercury and lead. And we can all agree that while a little heavy metal ringing in our earphones is OK, we really don’t want to find heavy metals in our water or soil. However, they’re in the electronics we use every ...

  • Using Data Loggers to Find Cooler Zones in a Greenhouse

    CAS Data Loggers recently provided the data logging solution for a small greenhouse currently cultivating several species of herbs for cooking and medicinal purposes. From potting to product, each variety has to be kept at ideal growing conditions before sale. From his own experience, the owner preferred ...

  • Experimental study of turbulence and vertical temperature profile in the urban boundary layer

    We observed the turbulence and vertical profile of temperature in and above the roughness sublayer (RS) using a tower, a tethered balloon and a Doppler sodar in Himeji City. A 3–D ultrasonic anemometer–thermometer was sited at a height of 54 m on the tower. The present results showed that in the RS, the ratio of friction velocity to wind speed, u* /u, observed under unstable ...

  • A simple methodology for surface layer characterization during diabatic extremes

    Increased global environmental awareness has fostered widespread use of remote automated weather station (RAWS) networks to monitor meteorological conditions, and reliance on atmospheric dispersion modeling for decisions concerning pollutant dispersion. Dispersion models require as input a characterization of surface layer (SL) heat and momentum fluxes and turbulence. Characterization of these ...

  • Fluorescent Lamp Recycling: Lighting the Future

    An analysis of the lighting industry shows a trend shifting from the usage of incandescent bulbs to fluorescent bulbs. Incandescent bulbs use more fossil fuel energy, are more costly and are less effective than fluorescent bulbs in the amount of artificial light they produce as fluorescents produce more lumens than incandescents. Usage of fluorescent bulbs, however, is not entirely without risk ...

  • Measurement Science and Technology Paper - Potential for improved radiation thermometry measurement uncertainty through implementing a primary scale in an industrial laboratory

    A primary temperature scale requires realising a unit in terms of its definition. For high temperature radiation thermometry in terms of the International Temperature Scale of 1990 this means extrapolating from the signal measured at the freezing temperature of gold, silver or copper using Planck's radiation law. The difficulty in doing this means that primary scales above 1000 °C require ...

  • Light-bulb Liars II: Mercury and CFLs

    The Washington Times ran a commentary July 11 that took a swipe at compact fluorescent lights. Titled “Light-bulb liars,” the article warns that broken CFLs are an “environment disaster in your family room” that “could poison the dog, the kid and the wall-to-wall rug.”To underscore the gravity of CFL dangers, the article then takes us through the Environmental Protection Agency’s step-by-step ...
