Testo® ultra-fine pressure probe - for heating check/4 Pascal measurement

The high-precision probe is used to measure differential pressure and temperature in conjunction with the testo 320 and testo 330. With additional accessories, the heating check (according to DIN EN 15378) and the 4-Pascal measurement can be performed. The ultra-fine pressure probe has no zero drift due to cyclic zeroing and provides highly accurate measured values. In addition, the ultra-fine pressure probe allows simultaneous gas pressure measurement and exhaust gas analysis with the testo 320 or testo 330.
