1. The barometer system does not contain any hazardous elements such as mercury, but it does contain fluid based on red-pigmented oil. The thermometer is filled with blue colored alcohol.

2. The scale is 4 times larger than a standard mercury barometer and with the highly colored fluid, much easier to read.

3. The barometer tubes are handcrafted out of high quality capillary glass. All glass tension is removed during production. This, together with the low specific gravity of the colored oil, insures safe movement and shipment of the barometer.

4. Due to the unique construction of the Eco-celli, there are no problems moving the unit from place to place or even placing it vertically. The rising or falling of the red fluid will be reduced by the construction in order to prevent mixture of oil and gas.

Now remove carefully the rubber plug and rubber hose. Insert the hollow glass plug that was included with your Eco-celli into the end of the red fluid tube. This plug prevents dust from mixing with the fluid but allows air pressure to enter the tube.

The barometer is now fully functional. Please wait at least one hour before taking pressure readings. This allows the instrument to reach the same temperature as its surroundings.

Located between the barometer (red fluid) and thermometer (blue fluid) is the barometer scale. Once the unit has acclimatized with its surroundings, you may begin taking air pressure readings.

Slide the entire scale up or down until the thermometer pointer is even with the top of the blue fluid level of the thermometer. By doing this, temperature correction is completed and pressure readings may be taken.

Set the tendency pointer on the barometer tube to the top of the red fluid level and take your reading off of the scale. The reading will be in inches. The next time you take a reading, you should see a difference between the location of the tendency pointer and the level of the red fluid. Unless there is severe weather approaching, air pressure does not change rapidly so allow several hours between readings.
