Testo 312-4 Pressure Measuring Instrument is a portable device used for fulfilling all measurement tasks on gas heating systems and on gas and water pipes. This Electronic Differential Pressure Gauge Testo 312-4 helps with fine pressure measurements that can be carried out quickly and reliably when checking the resting pressure and flow pressure of the gas, and when setting the correct jet pressure on gas burners and boilers. This Testo Pressure Meter has used to test newly installed gas pipes (load and gas-tightness tests), or on pipes already in use (serviceability tests) and can also be carried out quickly and in accordance with the law.

Applications: Gas Pipes, Burners, boilers, etc.

Testo 312-4 Pressure Measuring Instrument is used to measure values of up to 312-4 (max. 25,000 measurement values). The simultaneous recording of pressure and temperature allows the detection of unusual pressure fluctuations which are graphically analyzed by the Easyheat PC software, and can thus be easily explained to the customer

Features of Testo 312-4 Pressure Measuring Instrument:

  • Gas-tightness and serviceability test by pressure drop on gas pipes according to DVGW-TRGI 2008
  • Load test on gas pipes according to DVGW-TRGI 2008 with the help of the high-pressure probe
  • Checking the regulator by recording the measurement values over a defined period
  • Checking the gas connection pressure and gas flow pressure as well as setting the jet pressure on gas burners and boilers
  • Pressure tests on drinking water pipes with water using the high-pressure probe according to DIN 1988 (TRWI) as well as with air according to the ZVSHK information sheet.
  • Pressure test on waste water pipes according to DIN EN 1610 using the high-pressure probe
