It offers a large, easy-to-read barometer scale (28.80 to 31.00 inches / 732 to 782 mm) and a dual Fahrenheit/Celsius thermometer (32 to 122°F / 0 to 51°C). The device includes a calibration kit for sea level corrected pressure readings, making it ideal for accurate weather forecasting and educational use. Packaged in a sleek frosted acrylic frame, it combines scientific precision with modern design, perfect for professional and academic environments. ## Description The Eco-celli precision barometer / thermometer measures SEA LEVEL CORRECTED ATMOSPHERIC PRESSURE. The barometer consists of a 64-inch long U-shaped tube filled with a red fluid and gas. The pressure of this red fluid on the gas is principle upon which the barometer operates (Boyles Law). Adjacent to the barometer tube is a 32-inch long blue methyl-alcohol thermometer. A truly unique scale that slides between the thermometer and barometer compensates for thermal expansion of the fluid and glass tubing due to changes in room temperature and allows for accurate measurement of air pressure. Finally, the barometer scale is four times larger than a mercury barometer, making it much easier to make readings of air pressure. The temperature scale measures in Degrees F and C, while the pressure scale measures in both millimeters and inches. The Eco-celli comes with a calibration kit to adjust the unit for an altitude above sea level. The acrylic frame and glass tubes are packaged separately in the same box and require simple assembly by the final purchaser. The Eco-celli reads sea level corrected air pressure. This is the pressure used in weather forecasting. It is not designed to read altitude specific air pressure. The model E038.501 has been specifically designed for use in school science classrooms and school laboratories. It is made of durable clear acrylic 1/2 thick with very easy to read scales. The glass tubes are easily replaceable if broken. Additional calibration kits and red fluid are also available. Review: Nice Barometer , Interesting - Always wanted a liquid barometer. This one does not use mercury but a red colored fluid. You need to calibrate it for your location using the supplied syringe and tube to remove a bit of fluid until you get the reading matching a close airport. I used an aviation Metars sight, that shows a map with stations and current pressure. You can also use weather underground, just look at the closest stations to you and crunch the numbers, you'll probably see many stations close enough with measurements only .01 differences. After calibrating, the thing is very accurate. The first 14 hours after calibration it tracked the pressure change along with the airports of 0.1 " and I noted at the hundredths along the way, always within 1/100 . A true demonstration how the atmosphere presses against us all, good thing we press back. ## Features - Thermometer scale: 32 to 122 degrees F, 0 - 51 degrees C - Barometer scale readings from 28.80 to 31.00 inches and 732 - 782 mm - Frame size = 36.5 inches long by 5.75 inches wide - U-shaped tube: length = 32.28 inches, width = 1.57 inches - Mercury Free Barometer on Frosted Acrylic Mount ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000YOQ1RI | | Customer Reviews | 5.0 5.0 out of 5 stars (1) | | Is Discontinued By Manufacturer | No | | Manufacturer | Allivan Marketing | ## Images ![Eco-Celli Mercury Free Barometers Inspired by The Torricelli Barometer - Image 1](https://m.media-amazon.com/images/I/61Qb-gKlR2L.jpg) ## Questions & Answers **Q: Had for many years. What’s the best way to transport it to a new state without damaging?** A: Hello, Be sure to place the blue shipping plug into the open end of the red barometer tube to prevent leakage during shipment. If you are placing the barometer in a box, it would be safer to remove the tubes from the frame and remove the sliding scale from the tubes. Place each tube between two pieces of cardboard like a sandwich and tape them together. Do not stack anything on top of the box containing the tubes or they might break. Allivan Marketing has replacement tubes if that should happen. Also, if you are moving to a lower altitude, you will need to add red fluid to your barometer in order to calibrate it. Allivan also has additional red fluid. Good luck with your move. **Q: Can I purchase additional red fluid?** A: yes, you can buy fluid at barometersusa.com **Q: Is there a mounting hole?** A: Yes, there is a mounting hole in the frame. It is the black dot at the top of the frame in the picture. It comes with the screw which has a decorative cap to cover the end of the screw. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice Barometer , Interesting *by A***E on June 11, 2014* Always wanted a liquid barometer.
