testo 6351 – transmitter for low differential pressures
Units: volume flow, flow rate, differential pressure.
- No zero-point operation thanks to automatic zeroing
- Effective overpressure protection
- High long-term stability and repeatability
Delivery time: 5-10 working days
Delivery time: 5-10 working days
The testo 6351 transmitter series is specially designed for clean room applications and various hygiene zones in hospitals, for example. It is a highly accurate instrument and can be ordered with one of 16 different measurement ranges, from 0 ... 50 Pa up to -2 000 ... 2 000 hPa. The instrument has no zero drift due to the automatic zeroing. It also has no temperature dependency as zeroing is done at process temperature. They also have a very good overpressure protection of 140% of the measuring range.
- Zero in zero-point operation thanks to automatic zeroing
- Effective overpressure protection
- High long-term stability and repeatability
- Display (optional)
- Can also be delivered with other print areas, call for more info.
- Units: volume flow, flow rate, differential pressure.
