testo 312-2

Productdescription

The testo 312-2 and 3 manometers are DVGW approved and correspond to TRGI for all pressure adjustments and pressure inspections on gas heating boilers. Use the testo 312-2 precision manometer to check flue gas draught, differential pressure in the combustion chamber compared with ambient pressure or gas flow pressure with high resolution. Fine pressures with a resolution of 0.01 hPa can be measured in the range from 0 to 40 hPa. The versatile testo 312-3 pressure meter supports load and gas-tightness tests on gas and water pipelines up to 6000 hPa (6 bar).
