The Eco-celli barometer consists of a 64-inch long U-shaped tube filled with a red, non-toxic silicone 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 silicon 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 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 and pose no risk to the user or the environment.
