Fine pressure probe - for heating system checks / 4 pascal measurement
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.
- Carrying 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)
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.
