testo 312-2 Precision Manometer

The testo 312-2 pressure measuring instrument is suitable for carrying out pressure measurements when setting and maintaining gas heating systems. The pressure measuring instrument enables you to test the flue gas draught, the differential pressure of the combustion chamber in comparison to the surroundings, or the gas flow pressure, with a high resolution. 

  •          DVGW-tested
  •          Switchable measuring ranges with high resolution
  •          Alarm indicator for undershooting of freely adjustable limit values
  •          Print out of measurement data with the testo fast printer

Pressure measurements are a standard part of setting and maintaining gas heating systems (e.g. for determining gas flow and static gas pressure). The testo 312-2 precision pressure measuring instrument provides reliable services for these measuring tasks. 

The Testo pressure measuring instrument enables you to test the flue gas draught, the differential pressure of the combustion chamber in comparison to the surroundings or the gas flow pressure with a high resolution. The pressure measuring instrument enables precision pressure measurements in the 0 to 40 hPa measuring range with a resolution of 0.01 hPa. 

The testo 312-2 precision pressure measuring instrument is DVGW-tested and is suitable for pressure settings and pressure tests on gas boilers.

Practical features of the Testo pressure measuring instrument

The testo 312-2 pressure measuring instrument offers a high level of operating convenience in order for you to carry out pressure measurement efficiently. As well as the measuring values, you can also read the time on the clear display. The measuring ranges are switchable. And the optional testo fast printer means you can produce measurement data printouts directly on site.
