More about this item

The Eco-celli precision barometer / thermometer measures SEA LEVEL CORRECTED ATMOSPHERIC PRESSURE. The barometer consists of a 64-inch long U-shaped tube filled with a red fluid and gas. The pressure of this red fluid on the gas is principle upon which the barometer operates (Boyles Law). Adjacent to the barometer tube is a 32-inch long blue methyl-alcohol thermometer. A truly unique scale that slides between the thermometer and barometer compensates for thermal expansion of the fluid and glass tubing due to changes in room temperature and allows for accurate measurement of air pressure. Finally, the barometer scale is four times larger than a mercury barometer, making it much easier to make readings of air pressure. The temperature scale measures in Degrees F and C, while the pressure scale measures in both millimeters and inches. The Eco-celli comes with a calibration kit to adjust the unit for an altitude above sea level. The acrylic frame and glass tubes are packaged separately in the same box and require simple assembly by the final purchaser. The Eco-celli reads sea level corrected air pressure. This is the pressure used in weather forecasting. It is not designed to read altitude specific air pressure. The model E038.501 has been specifically designed for use in school science classrooms and school laboratories. It is made of durable clear acrylic 1/2 thick with very easy to read scales. The glass tubes are easily replaceable if broken. Additional calibration kits and red fluid are also available. Thermometer scale: 32 to 122 degrees F, 0 - 51 degrees C Barometer scale readings from 28.80 to 31.00 inches and 732 - 782 mm Frame size = 36.5 inches long by 5.75 inches wide U-shaped tube: length = 32.28 inches, width = 1.57 inches Mercury Free Barometer on Frosted Acrylic Mount Additional Details ------------------------------ Is autographed: false
