The Eco-celli barometer does not contain any mercury or other hazardous substances. It measures the air pressure, based on the compression of gas.
On the left side, you'll see a normal liquid barometer. The actual barometer scale is placed in the middle, and has to be set to the room temperature.
Liquid barometers can create a centre piece to any home or can provide a unique teaching aid for schools. This barometer allows students to actually see the effects of atmospheric pressure on the liquid in the barometer, a visual reinforcement missed when digital instruments are used.
