We offer Precision Manometers, which have been gone through DVGW testing. Provided pressure measuring instruments are offered with high resolution switchable measuring ranges. Also accoutered with alarm indicators, these can capably undershoot freely adaptable limit values. These instruments are appropriate solutions for carrying out pressure measurements when maintaining and setting the gas heating systems. Provided instruments enable the testing of flue gas drought, gas flow pressure, differential pressure of the combustion enclosure with a high resolution. Proffering a high level of operating suitability, these help in carrying out the pressure measurements in an efficient manner. The Precision Manometers show accurate measuring values of pressure on their displays.
