The Eco-celli Barometer is a patented new development in the ecological design of liquid barometers. The Eco-celli contains no mercury making it a suitable barometer for all schools and many hospitals. Mercury is extremely hazardous especially to the well-being of young children. We have documented cleanup cost for mercury spills that have ranged from $2,000 to more than $200,000. All of this can be avoided by using the Eco-celli Barometer.
The Eco-celli 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. A scale that reads in both inches and millibars (hPa) is also available.
The Eco-celli comes with a calibration kit to adjust the unit for an altitude above sea level. The frame and glass tubes are packaged separately in the same box and require simple assembly by the final purchaser.
The model E038.501 has been specifically designed for use in school science classrooms and 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.
