Dwyer DL72 | Differential Pressure Data Logger | ±2" w.c. (5.0 mbar)
For room pressure checks and duct air velocity monitoring, the Dwyer DL72 records differential pressure across ±2 in w.c. (5.0 mbar) plus temperature, running from its own internal battery. Accuracy on this ±2 in w.c. model is ±0.05 in w.c., with ±0.01 in w.c. resolution.
- Resolves ±0.01" w.c. with ±0.05" w.c. accuracy
- Self-powered by an internal lithium cell; uses Model DL200 software (separate) for programming and data transfer
- Withstands up to 4X rated pressure; stores as many as 21,500 readings
