Series HADP High Accuracy Differential Pressure Transmitter

Brand: Dwyer Instruments, LLC
Request Information
Does not ship to United States
Series HADP Differential Pressure Transmitter combines low ranges with exceptional stability, reliability and an outstanding accuracy of ±0.14% Full Scale.

All models come with NIST certificates and are available in unidirectional and bi-directional ranges as low as 0 to 0.5 Inches WC and 0 to 5 psid.

The Series HADP transmitters are extremely stable allowing for use in the most demanding applications.
Features
  • High stability at low pressure ranges provides exceptional accuracy for insuring tight control and minimizing costly out of specification conditions
  • Fast warm-up and response means no lag in monitoring and control that can cause time consuming false alarm conditions
