Fine pressure probe - for heating system checks / 4 pascal measurement
0638 0330Carrying out heating system checks and 4 pascal measurement with compatible flue gas analyzer and accessories
Simultaneous measurement of gas pressure and flue gas values
No zero point drift during pressure measurement (cyclic zeroing)
The fine pressure probe (with the appropriate flue gas analyzer and accessories) is ideally suited for carrying out heating system checks and 4 pascal measurement.
Cyclic zeroing means the fine pressure probe has no zero point drift and provides high-precision readings. In addition, the fine pressure probe makes simultaneous gas pressure measurement and flue gas analysis possible with the testo 320 or testo 330.
Fine pressure probe.
