developed specifically for use in heating system installations.
The main areas of use and measuring tasks are:
Gas pipes

• Performance of the pretest in acc. with

DVGW-TRGI 2008

• Performance of the main test in acc. with

DVGW-TRGI 2008

•  Determining the usability by means of pressure drop method
•  Pressure regulation testing incl. recording readings up to 24 h
•  Monitoring of gas connection pressure at gas meter
•  Monitoring of gas flow pressure at gas meter
•  Setting the nozzle pressure for setting gas burners/heaters
Water pipes
•  Leak test of wastewater disposal lines in acc. with DIN EN 1610
•  Performance of load tests up to 25 bar at drinking water

systems

Data transfer
•  Printout via testo IR standard printer
•  Data transfer to Easyheat PC software
The instrument offers the following characteristics:
•  Measurement location management
•  Data management via Easyheat software
