Digital and Analog Barometers

New Deals Page

Lab barometers are ideal instruments for measuring air pressure in specific environments. This instrument is perfect for forecasting the weather and measuring altitude. Air pressure environment instruments available at Thomas Scientific include digital, analog, and mercury barometers. Digital barometers carry a pressure transducer that converts the air pressure into an electrical signal and is ideal for various lab applications.

Barometers are designed to help you achieve clear and accurate atmospheric pressure readings and are ideal for experimental control applications. They can assist with identifying any abnormal pressure or potential leaks and minimize any potential hazards during lab experiments. Ideal for laboratory purposes, barometers also carry a secondary purpose of weather monitoring and prediction and can collect atmospheric pressure measurements to create a better understanding of weather and aid in future forecasting.

Also available at Thomas Scientific which you may also need are our air samplers .

What is the most accurate barometer?

Digital barometers are generally more accurate than analog ones because they provide precise readings with minimal manual error. They often measure pressure within 0.1 to 0.5 millibars of accuracy, making them reliable for detailed atmospheric data collection. Many digital models also offer automatic calibration, further improving their precision.

While analog barometers are still useful, they require regular maintenance for optimal performance. Factors like manual calibration or mechanical wear over time can affect their accuracy, which typically ranges from 1 to 3 millibars.
