Scholar Eco-Celli Barometer |
The latest development in ecological barometers, it contains no mercury so it’s environmentally safe and can be transported without worry.
Air pressure is measured by a red silicon-based fluid while temperature is measured by a blue colored methyl-alcohol. The error margin of temperature in the air pressure value is corrected by setting the moveable scale to the surface of the blue fluid; the air pressure can be read by setting the second index to the red fluid level.
Scale is 4X size making measurements easy to see even from the back of the room. Barometer scale is 975 mm/hPa - 1054 mm/hPa. Temperature scale is 0°C - 50°C. The U-shaped tube measures 82 cm in length with a total width of 4 cm and a tube diameter of 0.7 cm. Thermometer tube length is 82 cm with a tube diameter of 0.7 cm. Stands 99 cm and is 15 cm wide.
