ECO-CELLI

General

The Eco-celli is a new development in ecological barometers. Dingens Barometers registered and patented their invention on August, 24th 1998.

Key Benefits

• Contains no mercury
• 4 times enlarged scale
• Easy and safe to transport
• Environmental safe

Principle

• The with red silicon-based fluid and gas filled U-shaped tube is the barometer part of the instrument.
• Air pressure is measured by the red fluid.
• The right-hand precision-thermometer is filled with blue colored methyl-alcohol.
• Temperature is measured by the blue fluid.
• The error margin of temperature in the air pressure values is corrected by setting the moveable scale to the surface of the blue fluid in the thermometer.
• The air pressure can be read by setting the second index to the red fluid level.
• The amount and direction of changes in air pressure between the previous index setting and the current one, result in a reliable forecast.

Measurements

• U-shaped tube: length = 82 centimeters, total width = 4 cm, tube diameter = 0.7 centimeter
• Thermometer tube: length = 82 centimeters, tube diameter = 0.7 centimeter
• Thermometer scale: 0°C - 50°C
• Barometer scale: 975 hPa-1054 hPa (dimensions: 25 cm x 4 cm)
