PCE-DB 2 barometer
accurate barometer with memory for 700 readings

The PCE-DB 2 barometer is excellent for measuring absolute pressure in a range of measurement from -1000 to 0 to 2000 mbars. The barometer has an internal memory for 700 readings, as well as, an analogue and a digital output.
Atmospheric pressure, also called barometric pressure, indicates the weight of air due to the earth's force of gravity. Atmospheric pressure at sea level is 1013.25 mbars in an isothermal atmosphere. Before being shipped, the factory calibrates the PCE-DB 2 barometer to a barometric pressure of 1013 bars and altitude of zero (sea level). The user must take into account changes in altitude at the time of measuring absolute pressure.
At an altitude of 8m, the result is a difference of approximately 1 mbar. The display will show the actual value, dependant on the meteorologic situation and the altitude of atmospheric pressure. Often, the actual value is required as a correcting factor in exact measurements of physical parameters. Here you will find other similar barometers, but ones that will measure differential pressure.
Thanks to its ability to measure differential pressure, changes in respect to meteorological conditions or altitude can be observed. Furthermore, the barometer is adjusted to zero with the actual barometric pressure. Subsequently, the barometer displays the rise and fall in barometric pressure. Going up in a lift in a high building demonstrates the effect of altitude change and this can be seen on the display of a barometer. The PCE-DB 2 barometer has an ISO calibrations certificate that can be ordered separately.
This link shows an overview of our available barometers and if you need another type of measuring instrument, you will find a general list of products here.

  • Internal memory for 700 readings

  • RS-232 interface

  • Analogue output (-0.5 to 1V)

  • Optional software (Windows compatible)

  • Auto shut-off

  • Correction - zero value

  • Bag included

Readings are clearly sidplayed on the display of the DB2 barometer.

The PCE-DB 2 barometer as a positive or negative pressure meter
The barometers secondary field of measurement is for measuring negative or positive pressure with respect to the atmosphere. For this, the barometer has to first be adjusted to zero with the actual rate of compression at the location where the measurement is to be taken. To measure the rate of compression in an air duct or a tank, the tubes must be joined with a tube connector to the pressure connector of the PCE-DB 2. The display will show a signal in a range of -1000 to 2000 mbars. The barometer, as a handheld device, is easy to use to measure both negative or positive pressure.

Internal memory and interface
The barometer has internal memory for 700 readings that can be transferred to a computer. The optional yet affordable software allows the data to be read and for graphic representation of data to be generated, activation of the auto shut-off function, zero reset, adjustment of units and remaining battery capacity. Data can be exported to other programmers such as MS Excel.

Analogue output and data logger
The barometer can be connected, by way of its analogue output, to a data logger. The analogue output value in the range of 0 to 2000 mbar, absolute, is 0 to 1 volts.  For a differential adjustment, the analogue output value is modified according to the zero setting.
0 mbars = 0 volts, -1000 mbars = -0.5 volts, 2000 mbars = 1 volt.

Tube connector
A pressure measurement is successfully taken across an optional tube connector. The tube has a width of 5mm.
