Improved 8/1/06 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 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. Measurements: U-shaped tube:
length = 32.28 inches, width = 1.57 inches Thermometer tube: 32.28 inches Thermometer scale: 32 to 122
Fahrenheit Barometer scale readings from 29.00 to 31.00 inches and 733 - 788 millimeters Frame size = 41 inches long by 6 inches wide
The E728 scale is also available in inches and millibars (hPa) Model E728 Suggested Retail Price: $279.00 Click here for Eco-celli Assembly Instructions
