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 barometers  that have 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
Barometers to measure absolute pressure, differential pressure in respect to the atmosphere and negative pressure. air (atmosphere) due to the earth's gravitational pull. This pressure at sea level is 1013.25 mbars (milibars). Thermo-Hygro barometers are also known as climate meters. With these barometers, you can ascertain not only barometric pressure, but also temperature and humidity. AVM-4000 series barometers are multi-function devices for measuring pressure, temperature, humidity and wind speed. Before being used, the barometers and Thermo-Hygro 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 barometers to be used as handmeters to measure negative pressure in a laboratory.

Our barometers are digital devices and are specifically intended for use Calibration certificate for Barometers.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.

Barometers
Barometers are instruments that determine the atmospheric pressure. They have different forms and fields of application, but they are commonly used in meteorology. Therefore, it is a special group of pressure gauges. Barometers are commonly used in meteorology, and they are a standard tool that is included in almost any weather station.

Barometers are instruments that determine the atmospheric pressure.

In extreme latitudes barometers are often used as "time indicators" as good or bad weather partly depends on changes in air pressure. The reason for this is that the passage of a low pressure front leads to a change in atmospheric pressure. An increase in the atmospheric pressure is interpreted as a sign of good weather and a drop in atmospheric pressure of bad weather.

Barometers: Constant Pressure
In most cases a constant atmospheric pressure over a period of high pressure is sign of good constant weather (however, this "good weather" in the winter may mean a "grey skies"). This constant atmospheric pressure overlaps with pressure changes in 12-hour periods because of the logical changes between day and night. Changes in day / night cycle depends on the degree of latitude. The higher pressure values (up to 5 hPa / period) are close to Ecuador, while in Germany are below 1 hPa / period. Near the polar zone, values are close to zero. In some weather conditions the pressure remains constantly high for days or even weeks, so we could think that the barometers are defective.

Barometers: increase in atmospheric pressure:
This will depend on how quickly the air pressure increases. A slow and steady increase is indicative of improved long-term climate. A sharp rise (well above 1 hPa / hr) indicates an improvement of weather time and could be a sign of an impending storm of high pressure. Example: A low pressure front moves rapidly, giving way to one that comes later. The rapid and constant increase of more than 1 hPa / hour at sea usually causes strong gusts of wind. Even when the pressure reaches high values and remains constant, a strong wind can still continue blowing (up to several days).

Barometers, Atmospheric Pressure Drop:
Here, too, it will depend on how quickly the pressure drops per hour (or every 3 or 4 hours) and if the trend is uneven or if, for example, the pressure drop per hour is becoming more pronounced. A slow and steady decline indicates a change in time, it is usually the end of a period of good weather. At first the pressure drop is weak and will be recognised by the barometers slowly. The fluctuations are subject to the trend of the barometers. A sharp drop of pressure in barometers is a sign of imminent bad weather and the arrival of a storm. Depending on the degree of pressure drop, storms can be expected. The relationship between pressure drop per unit of time and forecasting of wind speed depends on latitude. In the subtropics, it is harder to calculate expected winds from a drop in atmospheric pressure. When the barometric pressure drop increases continuously this may indicate that we are near the center of a storm. A rapid pressure drop followed by a slow pressure drop may mean that the center of the storm passes over a greater distance.

These trends serve only to justify weather in some cases. Weather events also may be associated with increased atmospheric pressure. Therefore, the forecast established by the barometers is only a very rough idea.

Barometers to measure height
Height measurement with the barometers is based on an estimate of the height measuring atmospheric pressure. To determine the absolute height, this procedure is not accurate. However, it is sufficient to determine the relative height in relation to other points.

The following table shows the relationship between height and pressure barometers.
