Decorative Barometer
Free Shipping!The Eco-celli is a patented new development in the ecological design of liquid barometers. The Eco-celli contains no mercury. The U-shaped glass tube is filled with a red silicon-based fluid as well as a gas. This comprises the barometer part of the instrument. The barometers scale is four times larger than a standard mercury barometer making it much easier to read the scale.
The precision thermometer is filled with blue colored methyl alcohol. An increase or decrease in temperature can cause the fluid in the barometer to expand and affect the pressure reading. This is corrected by setting the movable scale, which is attached to both the barometer and thermometer, to the surface of the blue fluid in the thermometer.
The barometric pressure can be read by sliding the index attached to the red tube to the top of the red fluid level. This also serves to show the pressure trend as it remains in place as the red fluid changes level with the changing air pressure.
The Eco-celli comes with a calibration kit to adjust the unit for an altitude above sea level. The dark mahogany colored frame and glass tubes are packaged separately in the same box and require simple assembly by the final purchaser.
The model E728 has a simulated high gloss burl wood frame outlined in brass colored trim on the inside and outside edges. This is our most popular decorative frame. It turns an ordinary instrument into a featured element in any home or office.
