Differential pressure KP 321
The highly accurate KP 320 Differential Pressure Data Logger with wireless connection is the ideal high performance data logger for critical room pressurization applications.
The KP 321 has the benefits of our KP 320 data logger but with a larger differential pressure range of ±10,000 Pa.
Digital Differential Pressure Manometer Si-PM3
The palm-sized Sauermann Si-PM3 digital differential pressure manometer easily measures pressure.
Dual series
Dual: because it opens either on the right or on the left. Stop: because it allows the air escape safetly. Safe, because it also opens from the inside.
