No More Mercury!! The Eco-celli Barometer is a must in every science classroom! It is safe, accurate, and easy to use! The 162cm (64") long securely fastened glass, U-shaped tube is filled with red, non-toxic silicon oil. The adjacent 81cm (32") calibration tube is a sealed blue alcohol thermometer. A unique sliding scale between the two tubes compensates for thermal expansion of the silicon oil due to changes in temperature. The Eco-celli Barometer is so accurate, hospitals are purchasing it to calibrate their blood gas analyzers. And, since it contains no mercury whatsoever, it is completely safe in any classroom environment. It measures in both millimeters and inches of Hg. 92.7 cm high x 14.6cm wide x 3.2cm deep (36.5" x 5.75" x 1.25")Advantages of an Eco-celli Barometer
