Barometers
These barometers can be found in the section to measure absolute pressure, differential pressure in respect to the atmosphere and negative pressure. There are barometers such as the DB2 digital barometer that has an internal memory for up to 750 readings and an analogue output of 0 to 1 volts. These barometers are perfect to measure atmospheric pressure, also called barometric pressure, is an expression for the weight of air (atmosphere) due to the earth's gravitational pull. This pressure at sea level is 1013.25 mbars (milibars). Thermohygro barometers are also known as climate meters. With these barometers, you can ascertain not only barometric pressure, but also temperature and relative humidity. AVM-4000 series barometers are multi-function devices for measuring pressure, temperature, humidity and wind speed. Before being used, the barometers and thermohygro barometers have to be adjusted to 1013 mbars which is equivalent to the air pressure at sea level. The display shows the actual value, depending on meteorological conditions and altitude, which determine atmospheric pressure. DB-2 series barometers has a second field of measurement.  This serves to measure negative pressure or over pressure with respect to the atmosphere. This allows for the digital barometer to be used as a handmeter to measure negative pressure in a laboratory. If you don't find the barometers you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our offices on: +44 ( 0 ) 191 377 3398 and our technical staff will advise you regarding our measuring instruments.

The online shop has technical specifications for our barometers, or use the links below:

Our barometers are digital devices and are specifically intended for use in the industrial or labour sectors. They can be calibrated to meet ISO standards and can be used internally within ISO certified businesses. The certificate contains the information of the company that requests the ISO calibration. The ISO calibration can be ordered with the barometer or the barometer can be sent to us to be recalibrated to meet ISO standards. Generally, barometers are used in meteorology to forecast the weather and to determine if there is high or low pressure. Of course, our barometers can be used in this way, but they are primarily used to determine pressure in laboratories or warehouses.
